I haven't come across any. You generally don't see CL-x rated AC power cords, because most codes require high voltage AC cable that is run through walls or ceilings to be terminated into either a junction box or outlet box and receptacle.
So while not meeting code, if you still want an in-wall rated cable that would not emit toxic fumes when burned, what is the TV termination (IEC C13, C8, etc. or proprietary?) should someone find a cord with CL-2/CL-3 rating?
