This is basically little more than a committee, they can’t just create a new branch of government by fiat. It’s normal for vice presidents to head “task forces” or committees when the administration wants to focus attention on a given issue.
Cf. Pence’s role in the COVID task force and Space Council and Biden’s role on the middle class task force during the Obama administration.
When vice presidents aren’t breaking tie votes in the Senate, this kind of stuff is basically all they have to do anyway. What is it you think the VP is supposed to be spending their time doing?
