No, this depends on the function of "or" in the word. In the words door and floor, for example, the "or" is part of the root of the word and doesn't have another function. In words like vendor and grantor, the "or" is a suffix added to the roots "vend" and "grant", and the "or", related to Latin and French, means "one that does a specified thing". So if you can separate the "or" from a root, it is possibe (but not always true) that the noun relates to a person.
