Will FindFit, if given a linear problem with simple bound constraints,
and possibly NormFunction->(Norm[#,1])&, automatically treat as a
Linear Program (specifically a Least Absolute Deviations formulation
of an LP)? How might one find this out?

FindFit allows contraints to be specified and allows the
NormFunction to be specified as you wrote above. Given this, why
does it matter how FindFit works internally to arrive at a solution?
