Perhaps not all of them, but I just saw some NPC Knight use an old attack pattern... no video capture capabilities...
I clearly saw the NPC do a spinny-ish slash for the final hit of the combo attack.
An example of this specific old attack pattern. (Divine Avenger)
Baffles me deeply.
I'm not sure that they do entirely, Larry.
If I had to guess, they largely use the mecha knight AI, but an altered version of it. Why altered, you might ask? Because the AI can use guns, on occasion. Additional programming had to be added for this, and additional AI would be appropriate to make the knights act more knight-like, if you will.

I remember that level...
