I've been on my Transfem Illi type shi for months and i saw a post in the Illi McMillin cult about how Illi is canonically transfem and I literally couldn't agree more.
As a transmasc person (I'm not a transgender man but im definitely not cis and i identify a little bit more with being a guy I think) I still can like identify with Illi if that makes sense?
I also feel like in inokverse Frank is transmasc, i think I got that from a fic, could be wrong... Which is definitely less canon than Illi but i couldn't care less cause like that's so freaking adorable some t4t action 🥰
Anyways since inokverse is ALMOST completely fan-made (yap post for later) I do think we can use something so agreed upon, as canon.
On a little sillier note, I think it's Adorable how in all the mood boards and stuff so many people associate apples with Illi like i don't know where it came from but aweee
