The fact that more new particles have not emerged at energy levels the LHC can produce is a discovery--if I'm understanding the blog post correctly[1], it's the beginnings of a disproof of naturalness in supersymmmetry. It's not as exciting as if they had discovered hundreds of new things to study, but it's equally important. The point is though, these criticisms (that LHC might find nothing) had been making the rounds since before the LHC was built, while many promoters claimed we would for sure find evidence of supersymmetry. So while LHC may not have been a mistake, the right response now would arguably be to reassess fundamental theories in light of the new evidence accumulated at the cost of billions of dollars - not to go back and tweak the same old theories to suggest that many more billions and years need to be spent to make really really sure we were wrong. If late 1800s physicists had spent decades building ever more accurate devices for trying to prove the existence of the eether that held together the universe, perhaps some useful engineering or data analysis work would have come out of it, but it could also be a way for the field to go on an extremely expensive wild goose chase and stall out actual theoretical breakthroughs.
