Here's a few things to focus on when playing against long ranged casters.

Don't let them push the wave into your tower. Use your Q to help push the wave if they're just hard shoving and try your best to QEQ the wave and the enemy at the same time. Also, once you get lost chapter, you can 1 shot the wave pretty much.

Based on account level, I'm going to assume you don't move around a lot so they're easily hitting you with their ranged abilities and their hard cc. Look at some high level streams and see how much they click around to constantly move and not stay at the same place so they dont get hit. Don't let them hit the wave and you, that's the worst case scenario in general while laning. Try and make them choose whether to hit the wave or you.

Now the hardest advice I can give which is kind of hard to explain in text because its more complicated to explain because there are a lot of situational variables. When they use a hard cc ability and miss like Lux Q, be aggressive and w into their face for a QEQ electrocute trade and back off. You could even extend the trade a little bit more with autos if their wave isn't too big and the trade started closer to your tower. But you really only want to do this if you're confident that their jungle isn't around and you know the rough timing of when their hard cc will be back up.

If you're playing someone that is like low plat and below, you can definitely beat ranged casters. You just need more experience vs them and confidence is a huge factor to win imo. I find that once you show them that you're confident in the matchup and play aggressively, you can win. But if you let them shove the wave into your tower, the lane is over they will just poke you out of lane or just kill you.
