That’s a weaksauce argument IMO. The character was played by SJ. Depictions of this character necessarily have to be depictions of the voice actress.
Your argument may be stronger if OpenAI said something like “the movie studio owns the rights to this character’s likeness, so we approached them,” but it’s not clear they attempted that.
