How do I change the controller sensitivity using the VEXV5 block code
You can use a cubic control. By cubing the original drive value then scaling it back to 127, you can get finer control at lower speed compared to the original vex output, which basically equals to having a higher controller sensitivity.
You can red this post for more info

Yea no, you’re supposed to program your stuff not VEX.
Im not too experienced with vexcode blocks but this may be helpful:
