they take care of all taxes plus VAT expenses. so you can sell a game from there without registering as a company.
I am not sure about that. What I could find, they will report your earnings to the irs. Which might make some things more convenient.
But this would not change any requirement to register as a company, or how it is handled if you do not have a company, yet earn income from selling things.

videogames are a work of art, that means taxes dont apply
Where did you get this nonsense?
Some countries have exemptions for churches. Or actual charity donations, not the type of "donation" that is seen on Itch. But income is always taxable. It does not matter, if what you sell is "art".
