Its not true randomness and never is with these things but in this scenario its 'good enough'. I think this method of rng loot generation is fine for highly mobile enemies since it is very unlikely the player will kill the same enemy in exactly the same coordinates enough times in quick succession to generate repeat items. She can drop the purple biker pants which are like my favourite pants in the game so I was trying to get them off her with 3 sockets.
I did notice I could roll certain types of tank top or boots by killing her in different positions on the map. Rose since she has a patrol route and stands still periodically. I think it also matches with my experience of save scumming the balls off Matilda K. The Pacifica Ripperdoc guard certainly implies it.
