No. You should process the peptide ligand with pdb2gmx, not any external
topology producing sites.

Either will work. The syntax of the coordinate file is all that matters.
pdb2gmx can handle multiple proteins in the same file, provided they are
separated by TER or have different chain identifiers. pdb2gmx should then
produce two topologies (.itp files), one for each protein (the larger protein
and the peptide ligand).
