The way it works make in sort that it can't kill you easy at all, the system does not regulate bolus insulin which is without a limit, but a basal rate which is basically a rate of insulin distribution from slow to fast, even the fastest mode will not kill you, and if the system disconects for some reason pump uses a default average speed.

I understand that but the issue remains;

all a hacker would have to do is set basal rate to 100000% and then you have a "bolus that kills you".

Call it basal or bolus, it doesn't matter. The pump just pushes out insulin, and the amount can be controlled if you can hack the system.
