I have not seen anything, however that might be because the name does not have a meaning. I do understand that many names do have meaning. I do not believe all names have a meaning. In fact I have met people who's family name was what was written down (Invented) at Ellis Island immigrant station.
"Small beings can have small wisdom," the dragon said. "And small wise beings are better than small fools. Listen: Wisdom is caring for afterwards." "Caring for afterwards ...? Ker repeated this without understanding. "After action, afterwards," the dragon said. "Choose the afterwards first, then the action. Fools choose action first."

-Given that it's not her "original" name (retroactive though), that's actually an interesting thing to think about. Why did she choose "Lolth" for her new name.

I once tinkered with two possibilities for the origin of her name.
The first suggested it was actually a more “modern” [and poor] translation of her forgotten original name of Lilith - suggesting that it would then incorporate some of the themes associated with that name from Mesopotamian mythology into my version of Lolth in the Realms.
The other… is actually more of a thought experiment than actual lore I’ve established beyond a few notes in a notebook. Loosely, Lolth is a later rendering of what some in ancient times would call “lost” … suggesting Lolth’s origins are forgotten and that she may be a “lost” deity from another dead material plane/reality. Thus, the Lost deity became Lolth after later mistaken translations and curious pronunciations in various demihuman dialects. Lost to Lolth, for example.
