'How to add multiple lines in all files present in a directory using Ansible

In Ansible script, First I'm using find_module to find all files in a directory, and then I'm using set_fact to mention all commands that I want to add in all files and then I am using lineinfile module to add multiple lines in all the files, but it is adding all commands in list format ['line1','line2','line3'] instead of this I want these lines to be added one after another in all files. Below mentioned is the script

    tasks:
      - name: finding all files present in something directory
        find:
          paths: /etc/something.d/
          file_type: file
          patterns: '*.d'
        register: c1
        become: true
      - set_fact:
          lines:
          - "line1"
          - "line2"
          - "line3"
      - lineinfile:
          path: "{{ item.path }}"
          line: "{{ lines}}"
          state: present
          create: yes
          backup: yes
        register: c2
        become: true
        with_items: "{{ c1.files }}"
      - debug:
          var: c1
      - debug:
          var: c2

So... the old way, which I prefer, is with_nested:

set_fact:
  lines:
    - line1
    - line2
    - line3

lineinfile:
  ...
  ...
with_nested:
  - "{{ c1.files }}"
  - "{{ lines }}"

The new way, and I have no idea what escapee from a Ph.D. CS program came up with this, is to combine the lists:

set_fact:
  lines:
    - line1
    - line2
    - line3

lineinfile:
  ...
  ...
loop: "{{ c1.files | product | lines | list }}"

If all the lines are together, you might want to look at blockinfile.

I was able to add multiple lines in all files present in a directory by using below mentioned ansible script, However the problem now is all lines are getting duplicated, if I run this script again, Please suggest any way so that lines won't get duplicated in all files

    tasks:
      - name: finding all files present in something directory
        find:
          paths: /etc/something.d/
          file_type: file
          patterns: '*.d'
        register: c1
        become: true
      - set_fact:
          lines:
          - "line1"
          - "line2"
          - "line3"
      - lineinfile:
          path: "{{ item.path }}"
          line: "{{ lines[0]+'\n'+lines[1]+'\n'+lines[2]+'\n'}}"
          state: present
          create: yes
          backup: yes
        register: c2
        become: true
        with_items: "{{ c1.files }}"
      - debug:
          var: c1
      - debug:
          var: c2
