I don’t believe that we have libertarian free will in the sense that humans do not conform to the laws of physics.
I think it’s fine if you’re a concurrentist; as I said, there are many ways for god or god(s) to enact miracles. In a probabilistic universe, for example (a la certain interpretations of quantum theory), God can simply cause the wavefunction to collapse a certain way at a certain event.
I think that doing this means that God indeed changes the laws of physics. The laws of physics is not concerned of the tendency of causal agents, but on the actual physical consequences in the physical world.
As @dga471 mentioned, there is really no reason to say that the resurrection is an entropy reversal. I am pretty sure I did not miss the paper where someone went back in time, measured the temperature around Jesus’ corpse at the point of the resurrection, and found no change in temperature.
