  el: '#app-hook',

});

var todo = new TodoList({
  model: new Backbone.Model({
    items: [
      {assignee: 'Scott', text: 'Write a book about Marionette'},
      {assignee: 'Andrew', text: 'Do some coding'}
    ]
  })
});

Can you confirm the version of Marionette you are using? If it's version 3 LayoutView was removed and you should use View instead:

var TodoList = Backbone.Marionette.View.extend({
  el: '#app-hook',
  template: require('./app/templates/layout.html')
});

You can read about more changes in their upgrade guide.
