Alright assholes, to settle this I ended up doing the research myself.
The idea in the Japanese versions of the game is that Vivian refers to herself as female and uses female likenesses (calls the Shadow Sirens the "san shimai" meaning "three sisters", including herself, also refers to herself with "atai", which is a feminine pronoun). Other characters like Beldam refer to her with "okama", "otoko" and the like, effectively calling her male.
The important thing to note is that Vivian herself always refers to herself as a girl, however - in fact, it's not just her. In the Japanese version's ending, Goombella (who previously uses male pronouns taking after Beldam) cottons onto it, and refers to the group as sisters, including Vivian, as if respecting her choices as she comes to realise. In addition to all of this, her gender is never brought into question in the English versions, being unmistakably female with nothing to suggest otherwise, which was reportedly done intentionally to keep the game's age rating low overseas. While obviously this could mean that .they just removed this aspect of the character in other regions to avoid controversy, they notably don't make any passes to suggest that it also doesn't exist, what with Beldam still calling her ugly. However, despite this, the Italian translation mentions that Vivian "used to be a man, but now she's a woman and proud of it", further supporting the original Japanese text.
Going off of a character in the Japanese version of the game actively changing their opinion on her, as well as Vivian herself being insistent on calling herself female despite everything, and an official translation of the game actively stating that she is transgender, it's clear that the actual intention was to portray her as trans and happy with her choices. Remember, people used the same "otokonoko" argument with Bridget from Guilty Gear, only for her creator to come out and confirm she was transgender.
TLDR, she was written to be explicitly trans in the Japanese version and not just a trap, other characters were written to come to realise this and respect her choices, it was backed up other official translations. She's undeniably a trans woman, not male nor any kind of crossdresser.
Enjoy your fat ghost women.
