As far as I'm aware all the "demons" in SMT are canonically formed from the human collective unconscious, not in the explicit way that Persona's personas are but in that they're basically extradimensional entities and concepts that are translated by the human mind as mythological/religious imagery. Like a Plato's cave type of thing. So no, the majority of demons aren't legendary since there can be multiple of them, there just usually aren't. On the other hand you could have a decent selection of legendary humans based off the cast of each game. With that being said:
