Best plan of attack is have someone drop it off at the alignment shop and pay them to diagnose the issue. Could very easily be tires. I dont believe this model uses an electric steering assist system, but if so, a hard curb impact could cause this sensor to loose calibration. Easy to recalibrate with a GM tech-2system, but thats a dealer technician tool.

Tires definitely most likely candidate though.
Best of luck, and thank you for helping someone with dementia. It's a challenge, and I applaud your efforts.
