Michael Kim fbcd8e02f2 Change type annotations from LLMChain to Chain in MultiPromptChain (#11082) ...

- **Description:** The types of 'destination_chains' and 'default_chain'
in 'MultiPromptChain' were changed from 'LLMChain' to 'Chain'. and
removed variables declared overlapping with the parent class
- **Issue:** When a class that inherits only Chain and not LLMChain,
such as 'SequentialChain' or 'RetrievalQA', is entered in
'destination_chains' and 'default_chain', a pydantic validation error is
raised.

```
retrieval_chain = ConversationalRetrievalChain(
        retriever=doc_retriever,
        combine_docs_chain=combine_docs_chain,
        question_generator=question_gen_chain,
    )
    
    destination_chains = {
        'retrieval': retrieval_chain,
    }
    
    main_chain = MultiPromptChain(
        router_chain=router_chain,
        destination_chains=destination_chains,
        default_chain=default_chain,
        verbose=True,
    )
```
