The last time I read your account of this incident, you left this part out: "I was yelling at him quite a bit"
I can certainly sympathize with that reaction, most traffic stops are chickenshit and to be interrupted with that nonsense when in the middle of a medical emergency must be infuriating. But I think your FOIA requests looking for this file will never turn up anything, because the cop was almost certainly fucking with you. He figured you didn't like cops because you were yelling at him, not because of anything some computer file said.
"It says in your file that..." ... Uhh, hey, look at that, I think you are right, ...sure had me going there, LOL.
I really do hope they aren't "keeping a file on" me but I think I would definitely believe it was true, if they said it was so. I guess I'm easily conned. Generally trust authority.
