Panic Report - Can you help decipher?

Looks like Video card or RAM, but...

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

You may have a corrupt file system or a failing SSD (I suspect the latter):

Root disk errors: "Could not recover SATA HDD after 5 attempts. Terminating."

Try running Disk Utility First Aid on the volume (better to run First Aid on the hidden Container if you are running macOS 10.13+). Within Disk Utility click "View" and select "Show All Devices" so that the hidden Container appears on the left pane of Disk Utility. Even if First Aid shows everything as "Ok" click "Show Details" and manually scroll back through the report to see if any unfixed errors are listed. If there are any unfixed errors you will need to erase the whole physical SSD and restore from a backup or clone.

Try running the Apple Diagnostics to see if any hardware issues are detected.

Try running DriveDx to check the health of the SSD and post the report here using the "Additional Text" icon which looks like a piece of paper. See if DriveDx can run the SSD's internal short internal self-diagnostic.

Make sure to have a good backup.

You should always have frequent and regular backups.

The panics all seem to be in the Graphics subsystem. Since this is a Macbook Air, it will be using Apple RAM, and the integrated intel GPU, neither of which are known to fail (never say never, but very rarely).

Kernel Extensions in backtrace:
 com.apple.iokit.IOAcceleratorFamily2
    dependency: com.apple.driver.AppleMobileFileIntegrity
    dependency: com.apple.iokit.IOSurface
    dependency: com.apple.iokit.IOPCIFamily

You do have 2 kernel extensions installed

com.getdropbox.dropbox.kext	1.13.0
com.logmein.driver.LogMeInSoundDriver	411.18.87

DropBox has been a good citizen for years, so I do not suspect them.

I wonder if the LogMeIn sound driver using the GPU to do any sound processing?

At the minimum, I remove the LogMeIn kernel extension, and see if the issue stays or goes away.

If the situation stays, then I would suspect some kind of hardware problem. It could be RAM, as the integrated intel GPU tends to use RAM for its GPU buffers, and that might be a fixed range of RAM. Or it could be the GPU itself.
