The "phasor methods" is really just Fourier analysis in disguise.
As uart has already pointed out there is nothing stopping you from writing down the correct ODEs instead and solving them some other way; although you will probably find that solving them by using a Fourier transform (or a Laplace transform, they are pretty much equivalent in this case) is usually the quickest and easiest method; there are however cases where it is more conventient to look at the ODEs in the time domain.
