I agree to an extent, but it depends on how the other animals are depicted. If only wolves and bats are shown to serve Strahd, than players won't question the ravens. But we know that he at least controls the horses who draw his carriage, and we also know that druids worship him because to them, "he is the land." Further, since many things in Barovia (except humans with souls) are solidified figments of his imagination, then I'm not sure we can divorce other animals from him completely. Perhaps he just doesn't bother to control them? Perhaps some animals are just special (maybe ravens do carry souls?)?
