my grandma has her own car with the title in her name if i crash it can my grandma get in any money trouble if i do

It's possible.  Not only will she lose the money it costs to repair or replace her car, her insurance would be liable for your negligence in driving the car with her permissioni, which means that her insurance rates would go up.  If you are going to use the car on a regular basis, it is likely that her insurance would go up.  And, if she doesn't have insurance, or if it doesn't cover all of the damages caused by the accident, it is theoretically possible that she could be held liable for damages you cause if she was  negligent in entrusting you to drive her car (for example if you don't have a license, or habitually get into accidents).
