In at fault accident, other party is suing for damage and injuries.

I was in an accident back in August, and was stopped at a red light then rolled into the car in front of me because I looked back at my baby.

There was no visible damage to her car, and I had my car assessed and there was no damage to mine. I got it on dashcam and submitted it to my insurance.

Everytime the other party sees me now she becomes blatantly hostile and tries to talk to me and I have to remind her to continue speaking with insurance.

She is claiming damages to her car, and injuries and got a lawyer, to which she's now received several months of treatment for.

My questions are does hitting someone at like 5 km/h and no visible damage mean I actually severely injured her? She posts photos on social media of her going to the gym, bending over at the beach, looking up while she smokes joints, and going on electric scooter expeditions. She also would go on on social media about her back hurting because of her job. Will the adjustor determine that she must be as injured as she claims and just pay it out because she keeps wracking up all these treatments? What else can I do when she approaches me despite its all in insurances hands now? Do I deserve to be bullied and shamed for a genuine slow movement accident for the rest of my life?

What do I do if the insurance does pay her tens of thousands and she still tries to approach me? What do I do if she serves me with lawsuit papers?

I had accident forgiveness and there was no damage to my car so besides the severe anxiety and guilt from whenever she approaches me I'm fortunate that this hasn't impacted me much else. I also have a $1,000,000 liability policy so I'm not worried about her coming for my own assets.
