as it turns out, and is documented nowhere aside from a post on reddit, you can manually download your own root certificate - and iOS lets you install it without complaint.

if you're on an ancient iOS device, just point its Safari browser to this url: https://letsencrypt.org/certs/isrgrootx1.der

tap Install when prompted - and you've got working certificates again!

this just breathed new life into a 10+ year old iPad, which will become a bedtime plex viewer.
