The classic Babolat VS lists maximum tension as follows:
Team (17g): 62 lbs
Touch (16g): 68 lbs on some packages and 66 lbs on some others.
Having said this, I have strung 17g at 72 lbs many many times with no problems.
However, I can understand why your stringer would be apprehensive about going too high on the tension. Of course, if the string should snap, he would not want to be held responsible for that.
I string for myself, but if I were to ask a pro shop to string gut really high, then I would assure them that I would not hold them responsible for the possible snapping of natural gut.
