I have a big jug of Arista Premium Liquid Film Developer that has not been diluted. It has been open for a little over a year. The jug is almost full. Is it shot or will it still work?

By being opened if you mean that the bottle had been open at one time and the cap had been tightly replaced it may still be okay. I have had Tmax RS developer that had not been diluted but I slowly used well over the course of a year which remained okay. I've never used the developer you mentioned so I would use a test sheet before chancing an important negative just to remain on the safe side.
