Answer:
I know a doctor whose last name is Doctodoctor.
If it's "The last names Doctodoctor" then it sounds like you're talking about your last name.
Answer:
What is wrong with the sentence, "I know a doctor which last name is doctodoctor?"
The word "Which" is used. It does not make sense as "which" is usually used for non-living things.
So the correct version is:
I know a doctor whose last name is Doctodoctor.
