While many revocable trusts have the same person in all 3 roles, there is absolutely no reason you couldn't have 3 different parties involved. Many times you'll see family trusts setup with parents are trustors, their attorney as the trustee, and their children as the benes.
In real estate deals, I'd suggest a separate trust for each property with a 3rd party trustee (can you your attorney, or even a separate entity you use only for trustee-ship), and a single LLC as the bene for all the trusts. Remember, the only party on public record will be the trustee, along with the trust's name.
LLC costs ($800/yr minimum in CA for example) and maintenance can be prohibitive if you have a large number of properties.
Trust acts as a "cloaking device" and the LLC gives asset protection.
