The reports of crushed chainstays on LHT were the reason that Surly started to recommend against kickstands. They wanted to make it clear that a crushed chainstay was not a valid warranty claim.
I have an older LHT from first year of frame production, the early LHT appear to have had a different chainstay design, I use a single legged kickstand on my LHT. The color of the bike in the photos above from Bekologist suggest that his LHT is also one of the early ones from the first or second year of production. But even if these earlier chainstays were more robust, you have to be careful to not over-tighten the bolts.
Some have fitted a Greenfield single leg stand that clamps on the chainstay and seatstay near the rear dropout. The LHT spare spoke holder gets in the way for this type of mount. Some have done some surgery on the stand to make it fit, others have done some surgery on the spoke holder. I have one of these stands on a different bike (see photo) and this is my favorite type of stand. If I was going to try to put a kickstand on a newer LHT, this is the type of stand I would use, but I know in advance that I would have to spend some time making if fit with their spoke holder being where it is.
Note the painted "no bikes" zone where people apparently were leaning their bikes against the buildings.
Also, I recommend blue locktite on all kickstand (and rack) bolts.
