[Lovecraft] Cthulhu is a priest of Azathoth. Why does the "blind idiot god", who isn't even conscious of the world, need priests?

There are two portions to this answer:  the first part is that azathoth's worshippers are largely interested in keeping him asleep/placated.  If disturbed, he can pretty much just destroy the universe in a fit of rage and confusion.

The second part is that we just don't know what other motivations the gods may have.  The great old ones, and even more so the outer gods, are totally unknowable to humanity.  They are so far beyond our minds that just seeing them drives people insane.  We could never understand their logic or their motivations.
