Do you know of any other data analysis algorithm that fits 2-D analytic functions to galaxies and point sources directly to digital images, other than GALFIT? Especially to subtract lens light from strong lensing images?

The two most general, publicly available packages for galaxy image fitting (other than GALFIT) are probably Imfit and ProFit. (Note that I am the developer of Imfit.)
There is also Lenstronomy, which is specialized for fitting gravitational lenses; this might be more relevant to your particular needs, though I know very little about it.
