You'll need to use rowGroup.startRender for this - it gives you the number of rows in the group, so you could add a class if that is greater than 1 - e.g.

$('#myTable').DataTable( {
    rowGroup: {
        startRender: function ( rows, group ) {
            if (rows.count() > 1) {
                $(rows.nodes()).addClass('many');
            }
            return group +' ('+rows.count()+' rows)';
        }
    }
} );
