Could you give a few examples? I'd lean towards adjusting tooling if you can.
My spelling is often horrendous and I know it - but almost every dev I know of prefers to copy and paste anything that might be misspelled just because it's easier than taking the risk.
Similarly - how does does this get anywhere near causing a production outage?
I'd be tempted to view this as a blessing in disguise; this person sounds like they'll trip up more often than the rest, but if one individual can cause a production outage with spelling mistakes something's gone awry with your processes elsewhere. You have an opportunity to fix whatever that is now.
