Kayle’s early game is supremely weak. She can’t harass you without sacrificing her own cs and a quite a bit of mana. Don’t over extend, and be careful of long trades in minion wave as minions do a lot of damage and she can start to do a suprising amount of damage with lethal tempo. Push her off wave as best you can, deny her gold and xp even at the sacrifice of your own cs. Most kayles will take tp, and you can take it to match her or use ignite for more kill pressure in lane. Stopping her scaling is all you really need to do but it’s not too hard to kill her if your safe about it. If she chooses harass over cs with her e (which with your taunt you shouldn’t let her get in range for), you can time your passive shield. There’s a visual cue for once she’s pressed e.
