The case will be thrown out because the Senate is authorized by the Constitution to write and keep its own rules.
This is an idiot lawsuit asking the Courts to overturn the US Constitution.
Article 1 Section 5:
Each House may determine the Rules of its Proceedings, punish its Members for disorderly Behavior, and, with the Concurrence of two-thirds, expel a Member.
The filibuster is a Senate Rule authorized by the US Constitution. This case will go nowhere fast.
