Once you have access to the notebook again, can you stop MM the normal
way:

mv /usr/sbin/modem-manager /
killall -TERM modem-manager

and then run MM like this?

MM_SIERRA_APP1_PPP_OK=1 /modem-manager --debug

and attempt a connection?  Older Sierra devices allow PPP on the APP1
port (ttyUSB4 on your device) but unfortunately we have to whitelist
that.  It's actually impossible to test which tty accepts PPP on most
Sierra devices, so we really have no idea.  For examply, my C885 and
USB306 allow it, but none of my (four) 8775s or my 8781 allows it.
