and it isn’t referenced to pitch angle either
Wonder what else these experts got wrong?
Collins Dictionary refer to it as
the acute angle between the chord line of an aerofoil and the undisturbed relative airflow which would seem about right to me.
In their Aero Magazine they get it right as well other than the use of the word wind.

Angle of attack (AOA) is the angle between the oncoming air or relative wind and a reference line on the airplane or wing. Sometimes, the reference line is a line connecting the leading edge and trailing edge at some average point on the wing. Most commercial jet airplanes use the fuselage centerline or longitudinal axis as the reference line. It makes no difference what the reference line is, as long as it is used consistently. AOA is sometimes confused with pitch angle or flight path angle. Pitch angle (attitude) is the angle between the longitudinal axis (where the airplane is pointed) and the horizon. This angle is displayed on the attitude indicator or artificial horizon.
