Not sure what that actually means but it suggests they at least tried to get their training material legally.
First, where are you seeing that? And where does the "head here" link point? I'm not seeing it on the linked page or on https://elevenlabs.io/music-terms.
Second, that language is not saying "we got permission to use all the music we trained on". It seems more directly addressed at the rights they're giving you, as opposed to the rights they have to the training material. It could just as well be based on an opinion from their general counsel that it's fair use to train on all the music they downloaded, so it's "legal enough".
Third, and as I tried to emphasize above, legal is not the same as ethical. Even if they win the legal argument about fair use, it would still be shitty to take someone else's work and use it to train a model that put them out of business.
