• Your time complexity analysis are very well documented and explained. Great Work!
• Clean code and great variable names, makes it easy to understand
• in your set() method you can just use ll.replace() instead of deleting that key and append it. so it would change from

  ll.delete(node_data)
  ll.append((key, value))

  to

  ll.replace(node_data, key)

  it will improve the run time a little bit.
