I assume the studio were in charge of casting. It may also boil down to availability on the side of the voice actors, or perhaps they just wanted to use an entirely new actor cast specifically for the anime. On the plus side it doesn't overwork the VAs for the VNs, and it also gives other VAs a chance to hold the torch.

It also has the additional benefit of not dedicating just one person to a role, so will also ensure that there will always be someone to carry the torch if anything happens to any of them. A bleak thing to think about, but it does happen. This is why I'm concerned about Masako Nozawa voicing Japanese Goku and all his family members for so long.
