As for your second question, yes. Otherwise you have a perfect workaround that would mean a person likeness is free-for-all to use, but we already decided that is not acceptable.
That is not decided. There have been high profile cases were someone's likeness was explicitly used without permission, and they still had no recourse. It was argued the person was notable enough they could not protect their likeness.
Regardless, it appears debated if Sky even sounded like Johansson, which will make this very difficult for anyone to argue (being subjective and all). If the Sky voice actor was recorded prior to engaging with Johansson (which has been claimed by OpenAI), then it seems even more difficult to argue.
In the end, this will net Johansson a nice "go away" payday and then everyone will forget about it.
