Select all the Various Artists albums in either the Artist or Album pane,
then in the bottom Tracks pane:
select all (Ctrl+A), right-click > Edit Selected Items
Set the "Album Artist" field to "Various Artists", click Update
(Note: don't checkmark any other fields, only 'Album Artist')
Then right-click the 'Local Media' tree item and select "Add smart view"
Select a 2 or 3 pane view (up to you) where Album Artist is the first pane.
In my example below, I'm using a 3 pane view of Album Artist, Album, Album Art along the top (although, for the benefit of this post, I've hidden the 3rd-pane by dragging it to the right - original 3-pane Art view example here
