You're not actually selling them for profit on a per-use basis. While conceivably they could be monetized, that would probably not be sufficient to establish commercial use by itself, just as a movie with a parody clearly mocking some celebrity wouldn't satisfy the requirement (although the issue with specifically AI is not settled at the moment).
For instance, imagine you had a movie with a parody of Jerry Lewis, where you portrayed him as a vicious, abusive drunk, had him flipping over the wheelchairs of Jerry's Kids, and antics like this. Since the purpose would be clearly to mock him, it would probably qualify as parody. Now, imagine instead that you made a movie sort of like King of Comedy, but you'd asked Lewis to star in the movie and he'd refused, and you hired a lookalike to rip off his entire schtick and basically do what you'd have had Lewis do if he'd starred in it. At that point, it would be indefensible.
The issue is directly exploiting someone's reputation and image, to the person's detriment, and profiting specifically from that use. This isn't where the product being sold is the parody, and if people are watching it, it's to laugh at the person being parodied.
I actually think it's arguable, under the rule in White, even to go after the non-Kurt voice, but I personally wouldn't bother. I think that's taking the misappropriation concept too far, and outside the Hollywood knob-gobbling Ninth Circuit you might get smacked for it. However, I think it's utterly unquestionable, at least under current law, that the other pedotips voices and images are well over the line.
(This isn't addressing flaggotry, which would probably succeed. Ordinarily not a fan, but I don't give a fuck when it's Nick. Live by the flag, die by the flag.)
