Think you definitely could've taken him down. An atgeir is without a doubt one of the best weapons to take on a troll, just needed to re-consume your food buffs and potentially rest somewhere in case the fight would've taken too long and the buff expired. Dodging and alt attack atgeir is my main strategy against a troll.

I found that using a dagger with a shield strong enough to parry the troll is better, assuming you know how to parry trolls.
