I don't know for the gov. For HR, the best approach I've seen is to have source and links extremely prominent and have the bot speak like a mascot ("bip bip boop I'm the HR bot" style)
People don't read disclaimers nor warnings about the content, but usually won't come to the HR to complain a mascot fed them weird info they didn't bother to check.
