My thought is the Equipment Profile you’re using in BeerSmith is off.  I struggled for about a year to get my Equipment Profile, BrewHouse efficiency and Mash Efficiency accurate in BeerSmith.

Go into BeerSmith and record the BrewHouse efficiency you got from a brew you recently completed.  Now, go into the base Equipment Profile you use when creating a recipe and change the BrewHouse efficiency to the one you just recorded.  Now recreate a new recipe identical to the recipe you’re inquiring about using the newly created Equipment Profile. I will be willing to bet you will need more grain to achieve the same OG results.

I would also check the gap on the LHBS mill. I just use a wooden rod w sharpe markings, works for me.
Set your equipment losses too, and make sure you boil-off consistently. Doesn’t matter if you’re at 60% or 90%, the key is knowing. Then repeat it and plan for it.
