Is there any solution to the overflowing when the screen is smaller than the height of the toolbar?

Perhaps collapsing options, a dropdown menu, having the toolbar in a scrollable area? I couldn't find anything relating to this in the docs.

You can set the position of specific toolbar containers "blocks" to another place but else this is default Leaflet behavior.

map.pm.addControls({  
  positions: {edit: 'topright'}
});
