This action unsubscribes a contact from a Mailchimp audience (previously referred to by Mailchimp as a "list").

Or you could create a Journey like this, which would unsubscribe a contact from a Mailchimp audience when they unsubscribe from any Autopilot email:
If a contact enters this action who isn't subscribed to the Mailchimp audience, what will happen?
In this situation we won't take any action, since there is no existing contact in Mailchimp to unsubscribe.
Why do contacts sometimes take a while to be unsubscribed from a Mailchimp audience?
While we try to process things as quickly as possible for you, we are ultimately subject to Mailchimp's API limits. Please bear this in mind, particularly if we are using this action to perform mass updates.
The contact feed says "Mailchimp wouldn't accept" my contact, what does this mean?
Sometimes you might see this in a contact's feed when you try to unsubscribe them from a Mailchimp audience:
This may be because they weren't subscribed to the audience, or because Mailchimp has received too many requests to subscribe or unsubscribe the particularly contact recently.
You are welcome to try unsubscribing the contact again, however it is ultimately up to Mailchimp whether to accept the contact. Please contact Mailchimp's support team if you think a contact is being rejected when they shouldn't be.
