gen_vel controls the generation of random velocities. grompp follows it (but I'd have to check the code to see what it does if you use grompp -t). tprconv does not follow it.
The random seed is in a different variable, but only does anything if gen_vel=yes. I am not sure what the basis of your confusion about repeated calls to grompp is.
