It might be more accessible if they used ordered or unordered lists to
construct the tree. That would at least provide some indication of how
many nodes are in each branch. It would also help if it indicated to
the screen reader which items are expanded and collapsed--like you
mentioned.

Is it an option to alter the javascript that generates the treeview?
