Do the lienard wiechert potentials always give the same result as coulumb law+lorentz transformations?

Of course not. The Coulomb law+Lorentz transformations only works if the particle moves with constant velocity. Of course, this is quite a lot easier to calculate for this special case, but otherwise you need the Lienard Wiechert potentials.
