Local anesthetic systemic toxicity occurs when local anesthetic medications do their "thing" on the nerves in your brain and/or the nerves in your heart. Enough local anesthetic makes it slow way down or stop. Long or short-acting local anesthetics don't discriminate and perform as advertised and can make for a long or relatively short resuscitation. Oddly enough, IV lipids (fat) is bacon saver in these situation.
Local anesthetic medications can also can induce a seizure or more when enough hits the brain in a short time.
Anesthesia and surgery folks use it in very large doses/volumes and can also have a Maalox moment if things go unintended directions.

If I follow you correctly, you see the anesthetic as causal.
The cardiologist I saw immediately after my "death" seemed pretty sure it was the epinephrine included with the lidocaine that that caused the Bradycardia (very rapid uncontrolled heart rate) that caused the heart to stop, not the anesthetic in the lidocaine.
I've been told by doctors that epinephrine is often given to people to revive them after heart stoppage. Of course, not directly into a vein.
