You should be able to see the energies attributed to interaction with the ligand residue on a per-residue basis. (Along with what the terms are - you can read Alford et. al. https://pubmed.ncbi.nlm.nih.gov/28430426/ to get a description of what each of the terms "mean", so you can get a sense if the energy of interaction is primarily from hydrogen bonds or electrostatics or ...)
I'd probabably look into the residue_energy_breakdown application: https://www.rosettacommons.org/docs/latest/application_documentation/analysis/residue-energy-breakdown
