Scott, Live Nation and concert promoter Scoremore are also named in another suit seeking $1m in damages for Manuel Souza.
He filed a lawsuit on behalf of 21-year-old Noah Gutierrez and said he expected to file more for other alleged victims in the coming days.
In 2018, he pleaded guilty to a public disorder charge after he was accused of encouraging people to rush the stage at a concert in the US state of Arkansas.
When the commotion began, they thought it was a mosh pit, a popular dance at music events that involves people pushing against others.
