I'm having the same problem. I don't know if I used an AoE attack at some point in my stronghold or not, but, just wandering around my grounds I run into hirelings that attack me on sight. I don't know if, when I kill them, they are permanently gone or if, upon rehiring them, they remain hostile (in which case, maybe they're looking for revenge?), Regardless, it's mildly annoying.
