Are they suppose to be here even when you don't have the DLC?
No, in theory if Paradox cared about user-friendlyness and quality, they should not be here. But they are shown because for some reason the Custom Game Rules panel ignores all the DLC flags. It's not specific to La Resistance. For example, I don't have TfV but it shows Canada, I don't have DoD but it shows Hungary, I don't have MtG but it shows Mexico, and so on...
So even though all the options available in all DLCs are shown, only those that are valid for your specific DLC setup will work. Users can select anything and are left to wonder why it doesn't work.
Looking at the configuration file for the Custom Game Rules, we can see the AI behavior configuration is inconsistent, and would not work anyway if the Custom Game Rules panel were more restrictive.
