Does NEC 240.9 apply only to the bimetallic overload relays inserted directly inside the feeder circuit, or does it also apply to the CT operated overload relays?

Applies to any kind of overload relay, when used appropriately. OL relays would not, by the way, be "inserted into the feeder circuit". They can only be used (from a protection standpoint) in a motor controller.
