I might be late to the party but a quick way to avoid vars_prompt is to disable the interactive mode by doing that simple trick:

echo -n | ansible-playbook -e MyVar=blih site.yaml

This add no control over which vars_prompt to avoid but coupled with default: "my_default" it can be used in a script.

Full example here:

---
- hosts: localhost
  vars_prompt:
    - prompt: Enter blah value
    - default: "{{ my_blah }}"
    - name: blah

echo -n | ansible-playbook -e my_blah=blih site.yaml

EDIT:

I've found that using the pause module and the prompt argument was doing what I wanted:

---
- pause:
      prompt: "Sudo password for localhost "
  when: ( env == 'local' ) and
      ( inventory_hostname == "localhost" ) and
      ( hostvars["localhost"]["ansible_become_password"] is not defined )
  register: sudo_password
  no_log: true
