Camber not aligned properly, possibly due to running over road protrusion

[shittyprogramming]

I was rear ended and pushed into a car a couple months ago. After having the car repaired, I did an alignment at a dealer. The rear left camber was most troubling.

My first thought was that it was due to the accident, but I do recall running over a road protrusion a few months ago with my driver side tires, going about 40 mph or so. The front tire made a moderately alarming, sudden impact sound.. enough to make me cringe just a bit. The rear tire hit the protrusion the hardest and made a much louder impact sound that shook the car. I didn't notice any degradation in steering or handling, so I didn't go for an alignment. I do not currently have any issue with steering or handling. The wheel seems to be *slightly* tilted to drive straight, but could just be my seating position. Also looking at the accident photos... it looks like the bumpers did their job.

I took my BRZ to a Subaru-specialized mechanic shop recently and they were not able to find any problems from a visual inspection. They recommended front camber bolts and SPC rear lower control arms.

Is there any play in the way that the suspension components are connected? Perhaps they bolts shifted slightly after the impact? Any idea what are the highest likely causes for these issues? What should be my next steps at this point?
