No amount of unverifiable "records" (just pieces of paper provided by somebody who has a multimillion dollar incentive to show one outcome) will change my mind.
But if they can produce the actual voice artist I'd be more open-minded.
Altman's outreach, his tweet, and the thousands of tweets and comments talking about how similar Sky is to ScarJo is enough to win the case in California.
They asked SJ, she said no. So they went to a voice actor and used her. Case closed, they didn't use SJ's voice without her permission. That doesn't violate any law to any reasonable person.
All you know is that somebody being sued for multi-millions of dollars (and who's trustworthiness is pretty much shot) is claiming what they did. And frankly given the frequency and ease of voice cloning, there are very few people who can say with confidence that they know 100% that nobody at the company did anything to that effect.
What employee, if any, could say with 100% confidence that this model was trained with 100% samples from the voice actress they alledge and 0% from samples from Scarlett Johansson/her? And if that employee had done so, would they rat out their employer and lose their job over it?
