More like cooperation than rivalry. But you are right that the "talk therapists" typically are educated as (practicing) psychologists. Unless they are also MDs they cannot write prescriptions, and work together with those who can (when needed). Sort of like surgeons and anesthesiologists, although the analogy is weak, of course.

surgeons and physiotherapists was an analogy that sprung to mind

Yeah, that's good too.
