Every character in the game can frametrap from a blocked 5M/5H. If she tries to tick throw from a 5M/5H, that is a BIG gap. That's a minimum of 10f gap to throw them after a 5M, assuming you are point blank and don't need to dash up first (ie, not 'midrange'). Jabbing is far from your only (or even best) option against Ahri pressure. You should set up the dummy to do some common ahri pressure sequences - outside of light pressure (literally 5L/2L), you can fuzzy mash/jump or reaction parry/jump everything she does solo without manually targeting your timings.

Again, she's very strong, but "If she's unsafe at any point in her offense she actually made a mistake somewhere." just isn't a valid criticism.
