Publisher, I am a Reform Jew, not Orthodox. Although many or most Reform Jews do not believe Moses was divinely inspired, some of them still believe he wrote the Torah and that he existed as a major, or THE major, prophet. And I would think most Conservative Jews, also not Orthodox, do believe that Moses was divinely inspired; however, they have a different interpretation of parts of the Law. As you probably know, any individual rabbi may hold their own views; however, this does not mean they represent all of Orthodox, Conservative, Reform, or Reconstructionist Judaism. Still, any rabbi who claims that Abraham, Moses, Isaiah, Jeremiah, or any of the prophets may never have existed or is a composite of other people is intentionally or unintentionally undermining not only the core foundation of Judaism, but also Christianity, in my view.
