To better adhere to the Single-Responsibility Principle (SRP) from SOLID design principles, it's preferable to implement the "doubly linked list" and the "LRU Cache" as separate classes, with the linked list used inside LruCache to manage ordering.

You could reuse your doubly linked list class without modification if you store the key-value pair as a tuple.

Alternatively, you can use OrderedDict within LruCache to maintain order.

Could you update your code using one of these approaches?
