I've been told by someone involved with the AOA program years ago that only AA and DL have ordered that option in the U.S. What carriers have you seen have the AOA gauge on the PFD and/or HUD?

Waving the white flag here.
You are correct. Only “some” 737 NG’s have dedicated AOA displays. I am sincerely trying to avoid A versus B and just present facts.
However, any 737 NG with a HUD has, for all practical purposes, inertial AOA displayed.
FPV’s displayed on the PFD also provide some semblance of AOA. However, the A330 FPV in the FPA/TRK mode possibly disappears below the lower white line on the PFD attitude display at high AOA, possibly without any feedback to the pilot as to un-displayed FPA.
NG HUD FPV “ghosts” when non-conformal at high AOA, and NG’s equipped with the analog/digital AOA display have just that much more information available to recognize very high AOA conditions and correlate that info with other displays.
True, it is a customer option.
