The way I read it you hit their passenger side and rode away with minimal damage. If you were traveling anything less than 80 mph, at most you hurt her feelings and I bet the insurance people arrive at the same conclusion. Sounds like it might have happened even if you were driving instead of riding, so don’t sweat that part. You learned way more from the experience than the other person, she doesn’t even recognize a failure to see the danger and maybe next time it will be a Tanker Truck.
Chalk it up to experience and in future; anticipate that anyone within a mile might be out to run you down. ( or even just get in your way ) BTW: did she signal left in advance of entering that left turning lane, or lead you to anticipate she was traveling straight through ? Which goes to show you, fault is seldom so clear and you should never volunteer liability at the time of an incident. …You should have maybe anticipated she might drive straight at you without warning, that happens too.
One thing about riding a motorcycle, if you must take a longer route to avoid a dangerous traffic situation ( such as making left turns across a busy multi-lane roadway ) at least you get to ride more
