Can RASA be connected to DB2 table present in mainframe.

I don’t think you are connecting Rasa anywhere,

basically from the Rasa package, you determine an action that needs to be taken

an Action could be an API call , i am not sure about Python and DB2 drivers if it exists or not but you could write a middleware for your DB in SOAP/REST and use custom action(python class) to call the middleware service.

Can we have a dummy API which can be useful here. I need it to connect between RASA and DB2

I am not sure what you mean? what is a dummy API?
