Personally, I would assume it’s short for [name_f]Victoria[/name_f] or the like… It would be a bit weird for someone to assume your full name off a nn, especially if it doesn’t exist! I also think that with an ‘I’ ending, that gives it sort of a I’m-short-for-something-longer feel that [name_f]Annie[/name_f], [name_f]Ellie[/name_f], [name_u]Rory[/name_u] don’t have.
I found this other thread for ‘[name_f]Tori[/name_f]’ as a nickname:
That’s just my thoughts. [name_m]Don[/name_m]'t let me stop you from naming your baby what you want, though.
