Do 120V pool lights need GFI protection
If there isn't a "test" button on the breakers in question, then it's not a GFCI breaker. Look for a separate panel maybe mounted on the wall by the controller. 

Also the pool lights installed in your pool won't be 120V. They'll probably be 12V. There is a stepdown transformer in your control cabinet that lowers the voltage from your line voltage to 12V. Hope this helps.
