You seem to expect that the resulting string of {{ 'ansible_' + item +
'.ipv4.address' }} will then be 'retemplated', that won't happen
Also, don't use 'item' as that is reserved for ansible loops, the
following is the say to 'dynamically' access host facts:
{% for interface in ansible_interfaces if item != 'lo' %}
{{ hostvars[inventory_hostname]['ansible_' + interface+ '.ipv4.address'] }} ...
