Bayonetta 1 and 2 were originally bombs. The fact that a 2nd and this 3rd game even exists is pretty surprising. Sega seemed done with the series, but Nintendo took up the tab and paid to have a 2nd game made to spice up their Wii U exclusive library. I don't know what catalyst got the third game green lit, but it happened, and they spent an awfully long time with it too, so obviously, this wasn't a cheap game to make. With Nintendo, the money is obviously going to go to the game itself (game play prototype builds, trial and errors, and maybe development even had to be rebooted like RE4 and MP4, etc), and everything else is second. Voice acting has never been prioritized. I have a hard time time justifying boycotting a game that a slew of people will be playing in Japanese regardless, or barely paying attention to what's being said, as I doubt the game's narrative will be why people even play to begin with.
Big question I have is will this end up being the best selling Bayonetta ever? It already has more publicity going for it, in this era of social media. Or will it bomb, just like the other two (the ports and late sales must have really made some grinds if they can be considered remotely successful today, as they most certainly were NOT when they came out).
As far as Nintendo voice acting pay is concerned, I'm sure there is a lot of questions we could ask there. I mean, didn't they get Jenna Cox back to play Melia for Xenoblade Definitive Edition (and ahem). That girl's famous now thanks to Doctor Who. Chances are she played the role on the cheap, for the fans. Troy Baker did it with Catherine's Remaster or whatever it was, and implied he was willing to reprise Yuri for Tales of Vesperia's remaster, but Bandai Namco didn't ask him (likely thought he was outside their pay range as Mr. Baker has gotten much bigger and prolific since voicing Yuri many years ago). I don't think Bayo's original voice was being treated any differently by these standards, though I imagine she gathers that the title character is a big draw for the game and deserved more helping create that image for English speaking audiences. Nintendo and BN don't like playing much for voice acting. I have no idea how the Japanese VA side get's paid, considering the Tales of games seem to make a big deal out of the VA's they get for those characters, and they do a lot of BN sponsored PR and publicity for the games, like Hollywood actors do for their movies and clients. I don't think Nintendo will budge much on the VA budget unless they know the game is gonna sell 50 million copies, and even then, I don't see them doing anything different for Tears of the Kingdom from what they've done for BoW and Age of Calamity, and Chris Pratt is probably not voicing Mario for the next Mario Kart.
