How to correct a roll due to turbulence?
Your instructor needs some... instruction.  Inducing roll using rudder alone is something you do when you are right on the edge of a stall because a downgoing aileron can potentially induce a stall when right on the edge.   In a normal climb, using rudder alone is totally nuts.  

Apply only the rudder required to keep the ball centered with the application of whatever aileron is necessary.   If you needed all the roll power you can possibly get, you would apply full aileron and full rudder to use the resulting skidding to increase the roll rate.
