In the frame of one of the ends, the rod gains angular momentum - by falling linearly to the floor.
The torque is present, and required for a linear motion downwards in this frame.
Viewed from an inertial frame, the rod gains angular momentum. But in the accelerating frame of one of its ends, it does not.
