"item" is a variable that is always defined when you use with_items.
Ansible will parse that and confirm it exists and is defined.
You could pass "item" through Jinja2 first, which will use the value
it's defined to and fail if it can't locate that variable.
when: "{{ item }} is not defined"
I haven't done a serious effort to understand the Ansible/Jinja2 flow
but the above should work.
