Take your best infielder, usually the SS and convert her to catcher. You are learning softball 101 from the stands and that rule is no matter how good your pitcher is they can't win on their own. In the same situation in 8U we had a great pitcher and my daughter was the SS, we had the same problem, strike out nine and all nine ended up on first base on a dropped third strike. We moved my daughter behind the plate and started to win.
I did coach an all star team to nationals one year also and I am sure I looked like an idiot at times to the parents. The all star rules are different than travel ball rules for playing time and usually you have too many players to boot. We played several tune up tournaments like you are describing and struggled until we found the right rotation. In the end we lost two games all summer (once we started playing teams at out talent level) until we reached the national finals where we got beat five out of six games. Be patient it will all work out if the coach is as talented as you say he or she is.
