If this is your own personal machine, it probably wouldn't hurt. As
root:

mkdir /run/user/111
chmod 700 /run/user/111
chown user.group /run/user/111

As for your other question, /run/user/0 was probably created by a
program running as root for root. If there's a better way to do what
you want, or if what I propose isn't a good idea, someone else will
probably chime in.
