In the open world use the monster whistle item (its in the same menu as the chocobo whistle) and... thats it.

The thing is, I have the whistle to summon the chocobo, but there is no option to summon monsters. Unless there are 2 different whistles and I don't have it.

You should've gotten it automatically I think in chapter 4 or 5. If not check the store of the car, it should be there. Its called "beast whistle" and yes, its different  from the chocobo one.
