EBV has been linked to several autoimmune illnesses in recent years, so yes it’s treated seriously by those who have stayed abreast of that research. (It’s also been linked to certain cancers previously.) But as for whether it causes all human autoimmune illnesses, that seems a bit of a stretch. I don’t think you’d find many believing that. (Lots of infections can cause autoimmunity. The neurological damage / and long term post infection chronic fatigue that some COVID patients are suffering for example may likely be autoimmune related.)
