When I try to make an index group for the protein residue and the ligand molecule, the whole system is included in the index file.
I use these options:
r 166 (protein residue)
r 901 (ligand molecule)
then press q

By using make_ndx or a suitable command-line selection when running gmx rdf (see gmx help selections, but make_ndx is often much easier to use/comprehend for very simple cases like this).
