How about Renek or Tanky Fiora or Sion? And if it's low elo, it doesn't really matter if it's really a "top" pick. Just go ahead with Zed/Lissandra/whatever.
I think Renek does really well early, and if you're good, it's possible to dominate top and TP to farm others. Some games aren't winnable and provision matchmaking I'd say isn't that "stable", it gets better when you land yourself somewhere.
Fiora can sorta become really tanky especially with parry, so much mobility and all you need to do, is proc passive.
Sion's pretty fun, you can poke, slow and just be really annoying. I've got a Sion with Banner of command video that I think I shared before, it works wonders, especially against picks like GP (barrels deal 0 dmg to banner creeps). If your opponent comes in to fight you, just W>E>Q and let your banner cannon kill your opponent for you.
Lissandra's my go to pick usually at top. I'd build ROA, get some CD and go for Liandry's to help with dmg. Obviously not as tanky as say, Sion, but you can definitely soak up quite abit with ROA then freeze yourself, followed by zhonya if needed.
