The stories I heard on local radio and the (Andrew Joseph) story I read at USATODAY are far worse than any of the stories I heard about Love's high school days. I've never heard of this kind of behavior and sabotage before, are you simply discounting those tales?
I think you're allowing your attachment to UCLA influence you here by suggesting Lavar wasn't the root cause of his firing. Stephan's firing was blazed in permanent ink long before he was actually fired and it clearly was linked directly to the December break between Ball senior and the coach.
IMO, Lavar is far more than a pain in the neck and I pity the team that convinces themselves that he won't have the opportunity to cause a problem when his son hits the pros (unless it's the Lakers, they'll have less risk and I have zero pity for them anyway). I'm still a fan of the way Lonzo plays but questions over how he'll adapt to the differences in the NBA game and the concern over the influence and interference of Lavar makes him too big of a risk AFAIC.
I actually think it's quite possible neither Gelo or Melo ever play for UCLA, I don't think Melo will. So I'm not really too worried about the UCLA part of it.
The stuff about the substitute teacher part comes directly from a guy who posts on BRO and has for years. He lives close to Chino Hills Highschool and says it's well known they have had incredible turnover in athletic coaches there in many sports because of the part time vs full time teacher policy. They apparently have had a hard time getting and keeping full time teachers who also want to coach, so they hire coaches who are part time teachers and that's how Gilling got his job. He actually used to train with Lavar when he was younger, his first HS coaching job ever, was coaching the defending mythical national champs Chino this past year.
They've apparently had like 5 baseball coaches in the last 8 years and similar turnover in other areas. Baik the first basketball coach had by far the longest tenure of any coach there when he left, and again he CLEARLY left to get away from Lavar.
Love played for a coach named Mark Shoff in HS, he got benched for a game because he'd missed a practice or something like that, and I'll post the link to the whole story but he actually tried to get a court order barring the coach from talking to his son!

I think that was worse than anything Lavar has done.
A lesser known "incident" with Stan Love involved a kid named Clint Chapman who was a player in oregon the same time Love was there. Chapman was a highly rated Center and he verballed to UCLA and Ben Howland but it hadn't been announced yet. Love hadn't committed yet but effectively everyone knew he was going to UCLA. Stan Love was furious he didn't want another C in the recruiting class, and he didn't want another player from Oregon. So Stan Love reportedly told Ben Howland if you take Clint Chapman, Kevin is going to North Carolina not UCLA. Chapman even offered to redshirt as a freshman he just wanted to spend the year practicing against Love to improve himself, but Stan Love was insistent and Howland pulled the offer. Chapman went to Texas and told the story to the media before UCLA played Texas. We have a guy on BRO who was Chapman's AAU coach, he told me the whole story months before Chapman told it to the newspapers, so I had heard it but didn't know if it was true or not until Chapman confirmed it. Howland refused to comment on it, tough situation Love was so good you basically had to take whatever the dad dished out.
It's never been confirmed but lots of insiders will tell you the reason Kyle Singler went to Duke and not UCLA was Stan Love too, he didn't want another player from Oregon in the same recruiting class he and Singlers' dad apparently clashed over it and eventually they just gave up and went to Duke.
Lavar is a pain in the neck but at least so far IMO he has not been nearly as difficult as Stan Love was.
