Am I supposed to add olive oil to bread dough I did use a recipe on Foodnetwork?

I make my bread dough in my bread machine and yes I do use olive oil. It calls for 1/4 cup of oil and I use olive oil. Once the dough rises I remove it from the machine and usually make hot rolls.Am I supposed to add olive oil to bread dough I did use a recipe on Foodnetwork?
adding olive oil to bread dough allows the dough to become more elasticy and will roll out easier. it basically gives it more stretch. so dont use it in bread dough as the dough will become oily upon baking but it is very handy in pizza dough.Am I supposed to add olive oil to bread dough I did use a recipe on Foodnetwork?
I imagine that is to coat the outside of the bread.
