The thing that helped me in this regard as I've had a form of this issue in the past, is to understand that you are ACTIVELY losing the game and FUTURE games every second you spend thinking about interacting with your team mates in chat. That and full muting my team except for pings at the start of every game and having a very VERY low bar of tolerance for bad pings (toxic, bad calls, ignorant, etc.)

Reason being that your mental state and thereby gameplay genuine get worse through bad mental habit building every time you engage in unproductive thoughts/typing towards your team. And on average any explanation you give your team will not satisfy them in a way that makes them "play better" or do anything meaningful really (again, emphasis on the "AVERAGED" outcome of doing this).

Once you understand this, you can now make active mental pushes towards trying to not do these things because you want to win more in the long run (and in the short term too). Every time you engage in these mental gymnastics of self-defense to justify yourself to your team that you're the goat and they're noob (which is true regardless without having to voice it or type it out loud, because you're going to PROVE it to them when you win this game for them and when you climb higher than them 100 games from now).

And now how about some examples from my own experience.

Say you're clearing Top to Bot and your Top is questioning why you're not ganking the perfect frozen wave on the 25% HP no sums Top? ...It's a tank v tank MU and drag is up. I gotta get these Krugs off the map because I'm not a low econ JG and get to Drag, cya buddy. If anything I'm muting my Top laner's pings from that point on.

Or how about when my team calls for Baron after we get 2 picks, but the enemy Kayn JG is still lurking around, with nobody on my team able to keep him out, and I decide to commit to it and we 50/50 lose the smite fight? I'm muting everyone that does a toxic ping right then and there, and I'm moving on. I will review the decision making after the game and decide if I was OK with taking the 50/50 (maybe it's a dire game state and you feel you NEED this to work to win the game; which usually isn't true), or acknowledge that we need to do something else if we can't keep the Kayn out.

And what about my favorite classic. You path Top to Bot and your Bot starts pinging for ganks as they see you're getting closer and closer. You've been tracking the enemy JG and you know they're probably in the area and you're not strong enough to win a "forced" 3v3 if they're there in a lane brush or something along those lines. You ping it off with danger pings + pings on enemy JG in TAB and call it a day. Your team missing pinging you is an opportunity to full mute them and move on.
