Bah! An illithid that only eats animal brains is in no way necessarily evil.
Hmm...To get into Forgotten Realms details, Illithids are (AFAIK) 'refugees' from the Far Realms. The Far Realms are so strange that, basically, a demon or devil lord has more in common with a mortal than either has with *Anything* from the Far Realms. Basically, stick a Human, an Elf, a Warforged, a Dragon, a Demon, a Devil and even (AFAIK) a *Beholder* next to an Illithid and the 'One of these that does not fit' is the *Illithid*.
Could an Illithid be moral? Well, to answer *that* question (Scientifically and IG), you'd have to understand an Illithid...And FR *Gods of Knowledge* would struggle with *that*.
On the other hand, as a writer, that gives you a wonderful freedom - You're *Not expected* to explain Illithids, because *You can't*. So, if you have a moral Illithid...You *Don't* have to explain it.
