Staying under tower doesn't help anymore especially if that idiot is past 0/2 in just the first few minutes.
Just don't speak to him. It will just cause more problems if you respond in kind or aggression.
In match or hours after the match he'll learn to never pull that shit again, remain calm, work on his cs, positioning and being safe.
If it's a top laner struggling to cs but has good sustain or mobility to escape you can always do the singed stragety of just farming behind enemy towers then just flee.
Top lane has it easy when it comes to escaping the enemy top laner and jungler since bot laners don't go there much and most mid laners don't pay attention that there is a fight or a chase going on near top lane.
If you do get caught but minions or jungle monsters are nearby and you have no hope in killing any enemy player then you can just try to suck up as much cs as you can before you die.
I do this stragety If I'm having lane trouble as Nasus, Singed, Trundle, Gnar, Kled, Teemo, Ornn, Riven. This may look like a troll move to alot of people but alot of people will understand that this stragety does help in pushing towards enemy towers, getting your own money, exp and this does bait enemy jungler and enemy top to chase you (sometimes the mid laner). Doing this stunt then gives my allies information on where the enemy jungle,top,mid is and it makes pushing bot lane and getting dragon less stressful.
Also in alot of my top lane matches where I have been chased, the enemy trio that is Jungle, Top and sometimes mid. They get weakened from my attacks, jungle monsters who have been triggered nearby and chasing me which means alot of their spells and summoner spells will go on CD and will leave them exposed to get shutdown so my ally mid and ally jungler can $_$ cash in that thicc big boi money after I'm dead or just escaped with 1 hp.
I encourage you brave top lane players to give this a try, improve on your routes, save that flash for the right moment if you can.... and yes... that includes you, Sion mains/try hards to.
