When using gmx mindist -pi to check the distance between periodic copies and the simulation was done in a rhombic dodecahedron box are the distances correct, or do they use the corresponding triclinic cell?

The distances only depend on the three periodic vectors, these are the same for the dodecahedron an the triclinic cell.
