In similar cases, the court has found the company liable for using the books without paying for them (so they had to pay for every individual book) but the process of training an AI model was ‘sufficiently transformative’ (see: Authors Guild v Google) so as to not be considered a copyright violation.
They may win damages equal to the costs of the books that were used, but they won’t get the models deleted or be able to claim damages for the models that were created.
Why do we even allow these ‘businesses’ to exist?

They’re selling cyberweapons without any kind of regulations or restrictions.
