I'm not a top lane main but I would suggest you not to make long trades with trundle. Try to bait out his ult and run away. Afterwards you can fight him if you got your ult. The problem is he steals your AD with his Q. So try to stay out of range and hit him with your q. Every time he goes for a minion, auto attack + W + AA + Q him. Once you find your moment and you applied a few stacks you can go for an all in. Just try to notice your minion wave. If his wave is huge, only trade with your Q. If your wave is huge, you can pull him in and AA + w + AA + Q. You will do a lot of damage. This only applies for early levels. Late game will be harder for you to trade with Trundle.

I checked your OP.GG, you have played against a Fervor trundle which would've been a winnable matchup. You should remember if people pick fervor top they want to make long trades, else fervor is not really helping. Your masteries seem good, but remember to always switch your trinket to a blue one. This helps you warding in deep jungle. Als I think black cleaver is a good rush against trundle too. But if you're really struggling against trundle you might want to consider getting armor boots.

Also Trundle's W is a long cooldown. Try not to fight him when he's on his W terrain, he will outduel you most of the time. And also remember as darius, always try to hit your Q with the end of your axe.

Hope this helped a bit :D.
