The contention is that the specific translated text appears largely from illegal translations (i.e., fansubs) and not from authorized translations. And from a legal perspective, that would basically mean there's no way they could legally have appropriated that material.

Technically, everything is copyrighted. But your question is really about permission. Some of the known corpuses for AI training include known pirate materials (e.g., libgen), but it's not known whether or not the AI companies are filtering out those materials from training. There's a large clutch of cases ongoing right now about whether or not AI training is fair use or not, and the ones that have resolved at this point have done so on technical grounds rather than answering the question at stake.
