I'm sorry for your daughter's condition, but I think you are misinformed about type 1 diabetes. Most patients still product some endogenous insulin, it's just usually not enough. Like any chronic condition, it's a spectrum and there are outliers at both ends. I've learned to be very cautious about using words like "always" or "never" because of the odd cases that occasionally come up.

Diet and exercise are very effective at treating type 1 diabetes, just usually not sufficient. With a minimal or zero carb diet plus the right exercise regime, some patients find that they can go much longer between insulin doses while still maintaining good blood glucose control. In particular, I think a lot of people don't appreciate the necessity of doing resistance training to build enough skeletal muscle mass as a glucose sink.
