Definitely not. The creators of Pulp Fiction had a clear idea of the type of actors they wanted for their movie. The movie is known for its edgy and distinct characters, and the casting was focused on actors who could bring those characters to life in a very specific way. Kathy Griffin's acting style and persona are quite different from what was required for Pulp Fiction, so it's very unlikely that she was ever considered for a role in it.
There might not be an obvious direct connection. Kathy Griffin is a comedian known for her stand - up and controversial antics, while 'Pulp Fiction' is a classic Quentin Tarantino movie. However, perhaps Kathy Griffin has made some reference to the movie in her comedy routine, like making a joke about the unique dialogue or the cult - following of 'Pulp Fiction'.
Perhaps it's due to misinformation spread around. People sometimes make false connections between different actors and movies. Since both Kathy Griffin (known for her comedic work) and Pulp Fiction (a very well - known cult classic) are popular in their own right, someone could have wrongly thought there was a connection.
