[MCU] What exactly is the TVA supposed to do if someone like Doctor Strange or Wanda messes with the timeline?

Like slowing time won't stop the fact that both of them can just delete people and Strange has time manipulation as well if he has the infinity stone. Plus they can travel through portals. What exactly is to be done then? Hope for the best? Attack them in their sleep and hope they don't have any defenses?

They've got the benefit of choosing the battle field. They can jump into a timeline at any point they want, maximizing their advantage and their targets disadvantage. Everyone sleeps, shits, and let's their guard down at some point. They can also study not just the time line in question but any other similar time line to get an amazing scouting report of what they need to do. As long as the TVA agents are worth their salt they are essentially all powerful and all knowing. And they'll attack you before you even know they exist and what they are capable of. Basically, they only lose because they fuck up, not because of anything you're capable of.
