There isn't any reason for The Rings of Power to write Celeborn out of the narrative, so if anything, Galadriel saying Celeborn was killed in the war isn't a way of writing him out of the show so much as a tease of his eventual addition in a future season.
In episode seven of The Rings of Power Season One, Galadriel reveals that she and Celeborn wed long before the Second Age, but after he never returned from participating in the War of the Jewels, he was presumed dead. It is implied, though, he lives still.
What did Galadriel say about Celeborn in Rings of Power?
Galadriel mentions that after Celeborn went off to war, she never saw him again. That doesn't necessarily mean he's dead — only that she thinks he's dead. Remember the golden rule: No body, no confirmed death.
Galadriel was more tired and weary of Middle-Earth than Celeborn, and she just wanted to take the ship when there was one available. Celeborn had still things to do in Middle-Earth, and he would leave only later.
Celeborn was a Sindarin prince of Doriath, being the grandson of Elmo, the brother of Thingol; thus, he was the grand-nephew of the King of Doriath. In the early First Age, Finrod and Galadriel came to Doriath as guests of Thingol. There, Celeborn and Galadriel met, fell in love, and were soon wedded.
Sauron seemed to genuinely feel a connection to her, and part of that came from sensing the darkness inside of Galadriel. In that regard, his offer was really a seduction to the dark side.
Yet, since Tolkien does give family trees for other important Elves in the book, such as Galadriel and Elrond, it's clear that Galadriel is not Legolas's mother. (Besides, she is one of the Noldor, not a Silvan or Sindar Elf.)
It was as if the Ring had granted him a vision of what could happen if the great Elf were to wield its power. Jackson, on the other hand, used Galadriel's dark form as a visual cue for the audience. Specifically, it represented how she would become evil if she gave in to her deepest desire.
In The Lord of the Rings: The Fellowship of the Ring, Aragorn is given a long, Elven dagger by Lord Celeborn in Lothlórien on the day the rest of the Fellowship received gifts from Celeborn and Galadriel. He uses it at the Skirmish at Amon Hen and in all following battles.
How many children did Galadriel and Celeborn have?
The Lord of Lothlórien and Galadriel's husband.
Celeborn is hailed as one of the wisest Elves in Middle-earth, but it is clear that his wife Galadriel has the advantage, having been tutored by the Valar and the Maiar. Celeborn and Galadriel have two children together: a daughter, Celebrían, and a son, Amroth.
Galadriel in Rings of Power Bears Little Resemblance To Her Lord Of The Rings Character. The Rings of Power showed Galadriel as bitter and impatient. She was driven by a desire for revenge. Her father and three of her brothers has been killed by Morgoth.
Through her great-grandmother, Idril, Arwen was a descendant of King Turgon of the Noldor. Through her mother, she was the granddaughter of the Elf-queen Galadriel of Lothlórien. Through both of her parents, Arwen was a direct descendant of the ancient Elven House of Finwë.
6 Gandalf. As previously stated, Gandalf is a Maia and is therefore superior to Elves regarding power. Still, this isn't to say that an elf couldn't develop enough skill and power to defeat a Maia. As a bearer of one of the Three Elven Rings (Nenya), Galadriel would have an edge against Maiar like Saruman and Radagast.
While none of Tolkien's writing suggests Celeborn ever died and returned to Middle Earth, he did participate in many wars and could have easily been killed at least once, spent time in the Halls of Mandos, and then returned to a new body and reunited with Galadriel.
Celebrían was an Elf-lady of Lothlórien, the daughter of Celeborn and Galadriel. As the wife of Elrond, she was also known as Lady of Rivendell. She was the mother of Arwen and the twins Elrohir and Elladan.

Before the Company of the Ring left Lothlórien, each of its members was presented with a gift by Galadriel. Boromir was given a belt of gold which he carried in the journey until the Breaking of the Fellowship. When Aragorn, Gimli and Legolas laid him in his burial boat, the golden belt gleamed about his waist.
Teleporno is the High-Elven name for Celeborn. The element telep is Telerin for "silver," and orno comes from orna meaning "tall."

She also resisted being offered the ring of power by Frodo following his vision in the mirror of Galadriel, an immense test given the ring's seductive powers. Yet Gandalf's power level exceeds even that of Galadriel, as shown by his rebirth in the Two Towers.
Like Elrond, some of Galadriel's powers stemmed from the Ring of Power that she held in her possession. Nenya, the ring of water, had the powers of preservation and concealment from evil, which Galadriel used to create Lothlórien and keep it safe from outside influences.
So when she allows this incredible rarity to Gimli, she essentially gives him the three hairs that Feanor demanded of her, because she has looked into his soul and found that he has a good heart and that he desires them for nothing more than to treasure the beautiful days he spent in her lands.
Arwen probably got to know Legolas as her husband's friend and as the leader of the Elven colony in Ithilien. As Mary Tower points out, it is possible that they are distantly related, but it's nowhere stated.
Lord of the Rings: Legolas Basically Married Gimli. Legolas and Gimli's relationship is strong in The Lord of the Rings, even though it wasn't explicitly romantic in Tolkien's source material. The members of the Fellowship in The Lord of the Rings forge an unbreakable bond while on their mission to destroy the One Ring ...
It is later mentioned that Tauriel is a talented warrior and was therefore made leader of the Mirkwood border guards. Legolas, the son of Mirkwood's Elven king Thranduil, is indicated to be attracted to her, but as she is a lowly Silvan Elf, she does not believe herself worthy of him.
