I was thinking along the same lines.
Similar to the mitzvah of bikkur cholim, which helps those in pain by keeping their minds busy and not thinking about the pain- these kids may not be doing what they were doing if they were occupied.
I’m not sure what the situation is with anyone involved, but Sender Av did mention being up at 1:00 A.M. and having guests over. Maybe, if you’re up to it, invite them over for some cholent, beer and singing. Maybe they just need someone to “hear them out”. Think about all the sechar you can be getting for each minute they hold back from chillul shabbos.
A kid I once tutored told me about his journey from FFB to FFBBTAB (Frum From Birth, But Took A Break). He rebelled against his parents until they kicked him out of the house. A young couple took him in on one condition, he has to have a 45 minute seder with the husband every single day, no other strings attached. He told them that he needs a key to the house since he drinks and parties with his friends until early in the morning. He was shocked that they trusted him with a key, but “if they trusted me, I knew I could trust them”.
For the first few weeks the 45 minute “seder” was the kid complaining about everything that was bothering him, with the husband listening intently. When he ran out of complaints the guy started learning with him and he realized what he was missing out on. A few months later his own family took him back with outstretched arms.
