Illithids got it bad tbh, in at least one edition they're not innately evil but indoctrinated into a cult where they get mind controlled and ultimately eaten by a giant brain, that brain is the real villain.
However, you could make the case that gnome ceremorphs or gnome squidlings could pretend to be kids if a normal mindflayer wanted some fucked up version of a family for whatever reason.
is it time for drizzting the illithid until they become an evil species whose only members you can possibly meet are all chaotic good and hate their own people?
