Erm... no, because she abandoned Lolth way before the game's actual events. What she actually says (if romanced) is that she prayed for her lover to save her, but that there are no gods left to her. Otherwise if not romanced she'll just want a swift death to be free of the Absolute.
Not to mention that a Lolth-sworn player has a dozen dialogue choices to outright kill her for abandoning Lolth, and Minthara even has a unique dialogue in Act 2 where she dismissively talks about the Lolth-sworn player still following Lolth.
But anyway; I was merely referring to her pulling Eilistraee's sword out because there's poetic beauty in an exile of Lolth doing it. Not implying she'd actually ever follow her because she's obviously quite fed up with all the gods.
