You don't need the Grimm to be some invented species or aliens in order for them to have an explanation. The Grimm are said to have appeared after humanity and explicitly target humanity alone for the sole purpose of killing them. A reason exists for that by necessity. It could be the Grimm are like Weapons from Final Fantasy VII and were literally created by Remnant to fight humanity. Other explanations could be that they feed on negative human emotion because they are in some respect negative human emotion made manifest. Perhaps like ghosts or perhaps more like a curse. You want them to stay mysterious because you don't want it to be a dumb reason like the ones you mention, but there are other reasons.
