From the LBA and the partition table you can find out the partition involved. The next step is to find out the sector inside that partition, doing some math, and then, find out the file, which usually requires going through the entire list of files, the location of each file, and compare with the target sector. Hopefully there is a tool, specific to the filesystem, that does it.
Yes, there are google articles on it I found at some point, I should have taken notes. Hum... where...
Sometimes I'm fortunate. I have a note I wrote describing the procedure, but the LBA was on the SWAP, so I overwrote it entirely and done.

I repeated the method you describe above (amusingly, also ended up being /dev/sda3) ...which unfortunately turned out to be /home... also made a notes-to-self of the above routine (h/t). In the meantime, I decided (perhaps wisely, given what I just found ^^^ here), to purchase a replacement (EVO 860 500G) and just install that as a new /home. Interestingly, I've not hit any READ|WRITE errors on any files in /home in daily usage, so ... who knows which files may be affected. Perhaps I can keep the old disk in there as some `data` partition(s), and it might make the restore of /home easier (though I run double backup external drives... *shrug*) In the interest of completeness: `smartctl --test=long` results below.
