It's a bluff, OpenAI and Microsoft both have an carveout in that guarantee that effectively says "if we think you deliberately did copyright infringement with our tools, we won't help you".

And of course, conveniently, if you get a copyright infringement lawsuit, they can just point to that. A company promising legal defense is only worth the paper it's written on and there's always carveouts like that, with the likelihood of them being used probably being equal to the risk the company takes on with that promise. US Copyright lawsuits having pretty extreme fines makes them fairly likely to get used.
