There’s no way to know without looking at the vehicle. However, you paid this shop lotsof cash to fix it. Take it back and let him have another look. Any reputable shop will stand behind their work.
By the way, the struts and their mounts as well as the sway bar links with bushings would be perfectly normal needs for a vehicle this age. I really don’t see anything in your post to make me suspect the shop did anything unethical.
