It depends on the thermostat. There is no connection between the
thermostat being Galilean invariant and velocities of the particles
changing randomly (except for the fact that in the only such
thermostat available in NAMD, Lowe-Andersen, the velocities do change

The answer, of course, is also "it depends on the thermostat".

Here's my advice: do a Web search for "Lowe-Andersen". That should
bring up material that will help you answer your questions.
