My wife’s Malibu has those same arms bent. I brought it into the shop where I used to work and threw it on the alignment machine – there was enough toe and camber adjustment that I was easily able to bring everything back into spec. Not saying that will be the case every time, but I didn’t feel that the car was worth dumping any money into as long as everything is safe and functional (it has 243k miles and is beginning to rust).
When you replaced the struts, did you replace the mounts? Malibu’s frequently have clunking sounds from the rear from 2 places: The rear upper strut mounts, and the rear sway bar bushes.
