Geant4 does not calculate isotope production cross sections. For reactions like p + U at low energy, a compound nucleus is formed and decays stochastically into fragments. There is no cross section governing which specific isotope is produced. At higher energies the cascade models apply, but again the final state nucleus is produced at random, depending on the details of the intranuclear cascade.
The method GetInelasticCrossSectionPerIsotope is perhaps unfortunately named because it was used to get the incident collision cross section for a given Z and A and not the isotope production cross section.
