For the transtion metal complex, Cu(NH3)4SO4.H2O, is the water a ligand or water of crystallisation? I have looked online and most say this means its a water of crystallisation but one said water ligands are just written that way with salts.

If the water appears after a full stop then it's represented as water of crystallisation ... however in the solid lattice the water is attached as a ligand to the transition metal ion.
There is some grey area with the tetrammine complex due to a phenomenon called the Jahn-Teller effect. This means that the axial bond of the d9 complex ion is rather longer than the equatorial sites. The sulfate ion can be considered a balancing negative ion in the complex.
A better formula for this would be [Cu(NH3)4(H2O)2]SO4
