To restart MM, I use -
> sudo killall -TERM ModemManager
> ModemManager
(I don’t have systemctl on openwrt)

Also, can I have MM detect an already connected (plugged-in) USB modem, instead of waiting for a hotplug event?
Is there way to send AT commands to the modem via MM?
I tired -
mmcli -m 0 --command="E0"
error: command failed: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Connected: No AT port available to run command'

You need to disable MM, stop MM, and then manually start it. If you provide the full list of commands you're using I could try to see what the issue is.

I believe MM will receive and use all of those, yes. You can check that by looking at ModemManager debug logs.
