Good points - but a good point can be made that Drow are distinct enough as to deserve their own label. True, the Evul! dwarves do not, but demanding consistency from fantasy worlds and video games is a high ask.
Also, I regard Lollthsworn = umbrella term for Drow following the Evul! Elven pantheon, and Seldarine = followers of ANY God not making part of the Evul! Elven pantheon.
Larian was a bit inconsequent and a bit confusing here, I agree. But as Deity DOES. NOT. MATTER, no big deal.
