It could be that the best information about this presently comes, not from observation (since even our own Oort cloud is hard to see), but from simulations of solar system formation. I haven't read what these have to say about Oort clouds, but just intuitively I'd guess most stars with planets should also have an Oort cloud.

When two stars with Oort clouds come close, object in the Oort clouds won't hit each other much, but the gravity of each star will act to distort the other star's Oort cloud and send down a rain of comets.
