I like your question, but I can’t help but break it down:
A chopper is an informal name for a helicopter
Helicopters don’t (generally) fly near telephone or fiber optic lines
Telephone lines only carry around 90 volts AC at most at around 40 mA (give or take as more power draw sags voltage). You might feel it a bit on your tongue as it’s only roughly 3.6 watts at most. Volts tingle, amps kill.
The helicopter does not get electrocuted, the occupants would be the ones to be harmed
Electrocution implies death, “electrocuted to death” is redundant. It’s a portmanteau of the words “electric” and “execution”.
TL;DR unlikely scenario, in which case the phone line current will not be felt at all and the occupants are instead more likely to die in a fiery helicopter crash from the blades colliding with power lines and / or power poles.
I prefer to state it as power (watts) kills. To be truly dangerous you need voltage to overcome the electrical resistance of the human body and amperage to cause damage and burns along the way. Either one alone is relatively safe.
(And then there’s a whole other discussion to be had about frequency. DC pretty much only causes damage by burning tissues along the current path. Low frequency AC is especially dangerous because it can interfere with and disrupt nerve signals, causing muscle convulsions that force you to grip tightly onto the source and potentially disrupting the heart’s timing if it passes through the heart’s separate little nervous system. But at a certain point (around radio frequencies), higher frequency AC stops being as dangerous because the frequency gets too high for nerve cells to react to, and it goes back to only causing damage through burns, like DC.)

Also the occupants wouldn’t be harmed by the electricity because of Gauss’s law. Electricity stays on the outside of a conductor.
