I totally get that some of the voice actors are too expensive or racist or dead to reprise their roles or rent out their existing voice clips, but generally these types of games can and will hire and utilize substitute VAs. Like, I know it wouldn't be perfect, but a Tim Curry impersonator voicing Nigel Thornberry would be better than nobody voicing him.
Of course, the ball is in Nick's court, not the dev's.
