There's no abbiguity here, it's entirely textual and the unwillingness to accept that is merely regressive political nonsense. The reason Alluka's gender is refered to as being male in the past is because they assumed Alluka's gender to match that associated biological sex. The reason her family still refered to her using male pronouns in an intentional attempt to misgender her, the reason Killua used female pronouns is that he understands her and respects her gender identity unmlike her family. This is not something that's up for debate, it's the absolutely intention of the author on both a textual (throught he character herself) and (subtextual level through the character of Something).

If you politically disagree with that then that's on you, but wiki's on the other hand need to be accurate.
