So the normal reconnect happing every hour or so isn't working.
Yep. and it worked fine up until August 29.
Here because option changes (which seem strange, but
let's assume that
is okay) made openvpn tear down the interface ...
The message "Pulled options changed on restart ..." also appeared for
the first time on August 29.

I wonder if that might be some timing issue? I see it has happened 4
times since January 1, but then 8-10 times since August 29.

Maybe this suggests the tunnel is already gone and has taken the route
with it, so route and address cannot be deleted.

... and then fatally errors when trying to do some changes on the tun
interface itself via an ioctl. This doesn't sound like any problem on
the remote side, but rather a change local to you, e.g. a kernel
update with broken permission checks?
This machine hasn't been updated since 10.3 .... :-)
Still, let me reboot and see what happens.
