When you are in the situation of full left pedal and still yawing right, the only thing that will save you is when the aircraft weathercocks back into wind and the aerodynamics move you back to the pedal curve by dint of the new wind azimuth.
Full opposite pedal will stop the yaw - but that has to be caveated with the understanding that it might happen not immediately and more right yaw is likely to be experienced before you finally stop.
The problem is having the nouse to apply full pedal and leave it there until the yaw stops.
However, if the wind is zero or vey light and you are at a DA and AUM where the TR has reached the limit of thrust - you will keep going round until something else changes.
Certification for light helos only requires demonstration of adequate yaw control up to 17 kts crosswind but plenty of pilots fly in more than that, probably without considering the implications of that certification.
