Sorry for this. Toxic people are in general to be screened out and avoided. Has she always been like this? Seems like it from your post. If more recent, possibly some mental illness or dementia creeping in? Maybe time for you and other family to pull Dad aside and have a chat although it is his relationship to deal with. But you could let him know you all support him. He may not be doing anything for fear of hurting his relationship with his kids. Mental illness and addiction is tough. My ex, whom I am still friends with, finally had to cut her Dad off completely after years of verbal abuse and manipulation, alcohol abuse, mental illness and just plain being an ass.
