It seems you have a few misunderstandings of what happens with LED when they are dimmed. When dimmed the LED electronics shorten the pulses that the LED is driven. It no longer flickers with the mains frequency but rather a much higher frequency. You are using a slow shutter speed, that encompasses several full flicker cycles - so the anti flicker solution of the camera does nothing for you (it is a solution for shutter speeds faster than the flicker pulse length).  The problem you see is due to subject movement during the exposure, you get  the subject lit in different positions as the light goes through several pulses.
