Yes. Module *user* is able to generate a SSH key. See
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/user_module.html#parameter-generate_ssh_key

I guess user is trying copy authorized key from host A to host B if i didnt mis understood.

If so, use synchronize module with delegate_to parameter at task level

# tasks file for createuser
- include_vars:
   dir: vars

- name: create user sam
  ansible.builtin.user:
    name: '{{ username }}'
    group: '{{ groupname }}'
    shell: '{{ shell }}'
    generate_ssh_key: yes
    ssh_key_file: .ssh/id_rsa  
  become: true

does this do the same as

useradd sam

usermod -aG docker sam

su - sam

ssh-keygen -f ~/.ssh/id_rsa -P '' -q
