Avoiding VAC and other bans by my kids accounts /u/MadSin1337 Steam on Reddit

Hi, I have trouble finding out what exactly can cause a multi account ban. I often read about family sharing and same phone number or same e-mail. So i recently created accounts for my 2 kids to use but knowing kids do stupid stuff and my Steam account being very expensive by collecting games for over 15 years I want my risk to get any bans to be as close to zero as possible. My Kids are NOT in my steam family and they use different e-mail addresses, no phone number, no steam guard yet and they never use my PC but they use the same 2 steam decks as my main account. Of course I hope they never do anything stupid and cheat but is it safe that they use the same deck and would it be okay If i use my phone for their steam guard via the steam app? I am properly overly cautious but i would appreciate to see some official rules about bans.
