There is no way that the small piece of copper tubing is going to
contribute any harmful amount of copper to your tank. The CO2 can't
transport it and even if you somehow got water backed up into the
tubing the brief contact time won't come close to dissolving enough
copper to cause a problem.
A bigger concern would be a flimsy or fragile connection that could
break causing a sudden loss of CO2 and an increase in pH and if you
didn't have a back check valve water would syphon out of the tank.
