[2023] Do you ever see AP Katarina anymore?

Ever since her ult became on-hit I swear something like 90% of all Katarinas I've seen have gone AD and maybe 10% go "AP" in the sense that they're just grabbing one AP item like the Omnivamp mythic or Nashors and then going for AD items.

Is it just not worth going pure AP anymore after the on-hit change to her ult?
