Interesting situation during Resumption of Play

[MechanicGuy]

1st round of a BV playoff game, very close game.

Early 4Q, following a timeout, it's visitors possession, and the visiting team is late/delaying breaking the huddle while the home team is ready to go. My partner blows the whistle and places the ball at their disposal (midcourt, oppo table). The V kids start to rush over, but someone in the stands yells to his school's team to "PICK IT UP! GO!"...

...and the home team does just that. They grab the ball and inbound it lol.

Partner blows it dead obviously, and just awards the ball to V, who is now over there and ready to go.

My question, after the game, should more have been done? My first thought was a Technical foul, similar to touching the ball when the the thrower is holding it. Then I thought maybe a delay would be more appropriate, similar to a scoring team grabbing a made basket.

Is there any rule/casebook situation to govern such a goofy play?
