He frequently corrects his mother's statements, making her angry. He wants to oversee the meal planning, but chooses bad meal choices. He keeps putting off things she would like to do and will not hand over these chores. He is very difficult to talk to or difficult to plan out care for his mother.
Keep checking back for feedback from the community. There are many wise people with ideas.

This gives the family a chance to sit down with outside person and make decisions based on what is best for your Mother. You will get some very good feedback from the social worker. The negative family dynamics are usually held in check and just maybe this grown child will see the light of day! Best of luck.
Sometimes it's better to have someone else do the work and limit his visits to simply social exchanges. My BIL would battle with his mother constantly. Once she moved into ALF, their relationship improved. So in the above case, if a housekeeper/cook can be brought in to the picture, there would be less for them to fight about. They can go out to lunch or they can let someone else plan the meals and chores.
