Maybe a web based client made it past their web filter. There's a lot of them out there.

Wireguard to home. If they block that then try tailscale it should work
That implies that their organization allows adding net devices without authorization. If irc is blocked, modifying the network more than likely is too
+1 on this. Easiest way to get around school filters - used to have this setup when I was in high school (well, OpenVPN, but same thing just different VPN tech).
use a web irc client
A long time ago I used something like sockd to run a local proxy and then send that data to my personal remote proxy server over port 80, something like https://win2socks.com/ I think
Maybe there’s something better than socks these days.
Back then it worked pretty well, but I don’t think they were doing DPI. They (admin guys) did seem to notice large file transfers and seemed to be killing them manually.
I would assume most places these days will collect net flow data at least, so while https will protect the contents, they will be able to see the potentially unusual amount of data moving back and forth to your proxies IP.
I would suggest at least using a VPS to hide your schools IP address from the irc servers. And you may be in serious trouble if you get caught. If you’re in the UK you’re going to be risking jail time, and speaking from personal experience, they take this shit seriously.
So maybe just set up a personal hotspot.
Yes, use a proxy. Usually 443 is not blocked either, so an SSL encrypted solution is hard to block
There's a few WebSocket solutions out there. Basically looks like a normal HTTPS connection to something that uses a WebSocket, so unless they're decoding TLS and the HTTP session and somehow recognizes that this is a VPN and block it, it'll likely go through.
An ssh tunnel over port 8080 might work
It's not unheard of for the usual IRC ports to be blocked because it used to be used for botnets. Some servers may have different ports.
