Because like you said: Creatures of Grimm. Besides, again like you said, it's Grim not Grimm. That clearly states that Grimm is an unique word for Remnant and doesn't refer to the Grim word used to refer to death.

And they never said person, they meant an entity. Someone or something called Grimm who/which has gained enough fear from mankind to be referred as something of its own, therefore: Creatures of Grimm.
