Echoing CitrusFruits here. I did the same. Lots of LoL (and still do on the mobile version), but I still did extremely well academically and I continue to succeed in my career. I simply choose to fill my extra time with video games because that's what I like.

I don't think video games itself is necessarily the problem, it seems like the kid may be facing some intense external pressures in life that they need to escape to something; the escape just happens to be a specific video game.

I have a sibling (I'm omitting gender to obscure which sibling it could be) that my parents were extremely overprotective over; they had a lot of problems with just life in general. I had them live with me for around four years and covered as much as I could for them while their job was to just graduate from college.

They couldn't do it, and I ramped down my support for them over time and had them eventually move out. They said it was the best thing I ever did for them because it forced them to face life and they eventually got a job, found a place to live on their own, and also get therapy. They were diagnosed with ADHD. After getting appropriate medication, they were able to complete schooling successfully.

Sometimes you have to let the chicks leave the nest; let them fail and fight. Sometimes medication might be required to live a normal life. There's only so much one can do as a parent or a sibling, but in the end, it's their life and you need to let them live it out.
