As seen in the attached photo, with SelectionMode="Multiple" turned on, it turns into a huge mess. We need it so only the child nodes are selectable, and the group header rows are not.

For achieving this requirement, you can benefit from the SelectionChanging event of RadTreeListView. Through the AddedItems property of the event arguments you should be able to determine whether a parent or a child node has been selected. If a child node has been selected you can set the boolean Cancel property of the event arguments to True, thus disable the selection. Please take a look at the code snippet below.
