I saw an answer to a question told a new user to take their bike to their LBS. If somebody is new to cycling they're unlikely to know this is shorthand for local bike shop. I think using language like this is at cross purposes with stack exchange's style of complete clarity. Many questions refer to LBS, but shouldn't we stop using the term to increase our accessibility?
No, I don't think "LBS" makes sense to a first time user, or to many people finding answers from a search. It's a term known to much of the cycling community, but most people riding a bicycle won't know that term.
Even the term "Local Bike Shop" is problematic. The Walmart in my town sells bicycles, so it must be a local bike shop, right? But that's not what anybody saying "LBS" means.
Most answers should say something more like "Local shop that specializes in just bikes", but may need to be more explicit that they don't mean a big box store.
But it's contextual. Really depends on what you're seeing.
For a more universal guideline on this terminology: while making sure that an answer is helpful to the original questioner, also make sure that the answer is helpful to anybody who stumbled onto the question from a google search.

I might define the full phrase first time its used in an answer, then simply say LBS later. Same would go for "Front/Rear Derailleur" which becomes FD or RD if referenced again.
So to answer the question, LBS might not make sense to a first time user, but neither would other jargon words we take for granted, like Clincher or Bead.
We even have questions that confuse t[yi]re with rim with wheel with tube. At some point jargon is simply necessary to avoid waffle.
I'm a new user and I can tell you from experiencing it that "LBS" didn't make sense. I eventually understood what it meant by seeing it in different contexts.
I don't think it makes sense, and it would be a useful edit to say "Local bike shop" (LBS).
