The only “STL command” in OpenLB is the STL reader class. This class is an indicator, meaning it exposes both whether arbitrary physical locations are inside the enclosed surface and the distance to the surface. Such indicators can be used at various places in OpenLB, including the assignment of boundary conditions.

I suggest you take a look at the introductory sections of our user guide where the geometry setup is explained.

If you take a look at the cylinder case, you will see that the STL there contains the cylinder geometry, i.e. it can describe an airfoil in the same way. Of course there are also other approaches.
