For a case like this vgcfgrestore is probably the best option. man vgcfgrestore.
You need to see if you have archived vg copies that you can revert to before the "add" of the pv that went bad.
The archives are typically in /etc/lvm/archiive/<vgname>* on RedHat derivative OSes, not sure if they are different(and/or configured to exist) on other distributions.
grep -i before /etc/lvm/archive/<vgname>* and see which archive was made before the initial pv addition. vgcfgrestore -f <goodconfig> should work but I usually have to adjust command line options to get it work when I have used it to revert configs. I think in that case it will find the vg and pvid correctly. No cleanup should need to be done so long as the other device is completely gone.
And you will probably need to answer some prompts and warnings, and then reboot the machine, and/or do this all under a livecd rescue boot.
What kind of cheap ssd were you using? I have had really bad luck with ones without RAM. I RMA'ed one that failed in under a week and the new one also failed in a very similar way in under a week.
