Just speculating here, but GM may be forcing dealers to buy the tool because damaged cells might need to be discharged quickly in order to avoid a 'thermal event'.
NHTSA's Volt caught fire after sitting for a while, so they probably don't want damaged Volts sitting on dealer lots with live batteries while they're waiting for a tool to arrive.
