Questions about taxes as an OF creator

I know there’s several things you can write off for being an Onlyfans Creator. Gym, travel, nails hair, etc. In order to get these sort of write offs, would you need to structure my onlyfans as an LLC? Or could I do it as an individual come tax season?

Also, if there’s any other really cool tax loopholes that I don’t know about, feel free to add those in as this is very fascinating to me.
