Yes, HLBM based FSI interacts well with refinement. I have e.g. a working setup where I coarsen away from a wall-modeled rotor.

There will however be issues when the FSI element moves through refinement regions (due to this not being implemented yet and refinement in general being a very manual process right now in OpenLB). Can you describe your setup in more detail? I assume you converted the static sphere into some moving FSI element?
