DeadLoverFortNikel "Nath Dyer" [CREA:000C654F] shouldn't have any AI Packages, and he probably shouldn't have any actor animations either, as he is a dead NPC that spawns with 0 health (but I suppose you could technically resurrect him with the Staff of Worms, so I'm not sure about removing his actor animations).
There are some other 0 health zombies that still have AI Packages here too:
DeadZombie "Zombie" [CREA:0001B79E]
DeadZombieCorpse "Decomposed Corpse" [CREA:0004FEEB]
XPEbroccaWife "Rotten Corpse" [CREA:0008238C]
SEDeadZombieCorpse "Decomposed Corpse" [CREA:0008E9E6]
