If that’s true, that’s certainly not ideal. If I were in a crash and insurance paid for only one side, I’d do the other side out of my pocket.

MM’s above explanation above is good. Some of the alignment angles are built into the suspension parts (e.g. strut) geometry and not alignment shop-adjustable However it is sometimes possible to elongate (file) a hole in an existing part, which allows the shop to modify the angle slightly by positioning the fastener slightly toward one side of the elongated oval. Some replacement struts already have the elongated holes. I expect many alignment shops may be reluctant to do this however, as if done incorrectly, could produce a suspension geometry the manufacture hasn’t safety tested.
I concur that the rear angles look the most problematic, probably where the solution to the pull is. Note that it is possible to have perfect alignment on each wheel, but not perfect for all 4 wheels, b/c for example the front and rear wheels are not aligned with each other. Sometimes this is called dog-tracking I think. Google will tell you more.
Theory not supported by facts. The front alignment looks pretty good. Struts don’t wear like brakes. At the end of their life they fail, usually by leaking. This is not causing your left lead.
