AI companies could certainly release the scans of any book that is no longer covered by copyright in the USA, for free download and get some positive publicity for a change.
I do wonder who is running PR at the major AI companies, as they seem rather insensate to how they are perceived...
PR only cares that the company is percieved as unstoppable & inevitable.
If their PR teams did have a response to these actions, it would be something to the effect of:
"would you rather china destroy all the books and gatekeep the knowledge?"
The other thing they could be doing is using some of that lobbying money to try to reform copyright law to allow them to release the scans that are still covered.
It would likewise earn goodwill from a lot of people.
