Does the number of other groceries in my fridge affect how long it will take for a room temperature pitcher of water to cool down?

The less space for air in your fridge means less heat transfer every time you open the fridge door.  This means that a full fridge (containing already-chilled groceries) has a head start when you first place the pitcher in, while an empty fridge needs to spend extra energy cooling the air down again.

That said, assuming the starting conditions were somehow identical (as in, you teleported the pitcher without opening the door), then the extra air would aid in cooling, as it can circulate the heat away from the pitcher better.
