One interesting legal caveat is that the Sky voice isn't "ScarJo", it's ScarJo as acted in the movie Her.
An issue with voice actors having their voice stolen by AI models/voice cloning tech is that they have no legal standing because their performance is owned by their client, and therefore no ownership. ScarJo may not have standing, depending on the contract (I suspect hers is much different than typical VA). It might have to be Annapurna Pictures that sues OpenAI instead.
IANAL either, but that's not the caveat you think it is.
Bette Midler was able to sue Ford Motor Co. for damages after they hired a sound-alike voice: https://en.wikipedia.org/wiki/Midler_v._Ford_Motor_Co. Ford had acquired the rights to the song (which Midler didn't write).

Forbes had a good story about performer rights of voices: https://www.forbes.com/sites/rashishrivastava/2023/10/09/kee...
IANAL of course.
