I’d expect Galadriel to be very much in the “The only good orc is a dead orc” camp. That’s based purely on vibes, I don’t recall anything about it in the LOTR books and I never could finish The Silmarillion.
Tolkien also wrote the orcs as pretty explicitly “always evil”, at least in lord of the rings and the hobbit. He seemed to be conflicted about making an always-evil race, but that IS how it’s written in those books.

On the other hand Tolkien was quite clear on that the story was told from the perspective of the protagonists. Not least through the strong insinuation that the in-universe book that Bilbo started, Frodo continued, and Sam finished, is if not the book we are reading, at least an important source for it.
Lord of the rings telling them as evil mostly shows that’s how the fellowship saw them.
Could you stop by my office? Bring your cardkey.
Frodo: Don’t blame, me. You guys made it
The elves of Gondolin predated Galadriel iirc. So, Galadriel’s ancestors made the sword.
Galadriel had nothing to do with Gondolin but she was definitely in Beleriand at the time. She was around to experience the light of the trees and make her way to Middle Earth with the Noldor.
