Crab,
As you rightly state....there will be a yawing movement but that can be minimized somewhat by application of Collective ( a quick pulse), then as the aircraft touches down any other yawing will have to be followed by cyclic as the aircraft comes to a stop.
The point is even with no Tail Rotor Control by use of the Tail Rotor Pedals.....one does retain some control by application of Collective (if no engine power) and use of Collective and/or Throttle if the engine is running.
If you do not have a usable Tail Rotor....you will have to live with the fact the nose may not remain pointed in the direction of travel. The key is to have as slow a ground speed as possible....and follow what yaw you have with cyclic to keep the aircraft upright.
