The PPV was the first event to feature on Triller Fight Club as part of the American social-networking video service's plans to hold boxing cards.
But Triller, which helped promote 2020's Mike Tyson vs Roy Jones Jr fight, will now take action against several sites and streamers who illegally streamed Paul vs Askren.
According to Yahoo! Sports' Kevin Iole, Triller's US lawsuit will target 11 websites and 100 unnamed persons.
And the online service claims that the aforementioned 'entities' had two million streams that resulted in a loss of $100m.
Iole confirmed that the lawsuit was filed in the United States District Court for the Central District of California.
A Triller spokesperson told MMA Fighting: "It's shocking to think a theft so grand can be done so blatantly and brazenly and steal with no remorse.
"There is zero difference between what they did and walking into a market stealing tons of a product and selling it at a discount in the parking lot.
"It's neither civilly nor criminally any different and we are prosecuting to the fullest extent of the law.
"There were far over two million illegal streams, akin to hundreds of millions of dollars.
"[...] People put a lot of hard work, time and money into creating a product for the consumer and having it stolen and resold is terribly damaging.
"The good news is they are not protected by VPN masking or other firewalls as their activities are criminal and grand theft so we will ultimately find them and prevail not just for us but for content creators in general.
"We intend on working closely with the authorities as well to stop this highly illegal behaviour."
Paul notched up his third professional boxing win on the night after he stopped Askren in the first round at the Mercedes-Benz Stadium in Atlanta, Georgia.
The Triller Fight Club is slated to return on 5th June in Miami as boxing legend Evander Holyfield makes his sensational return against Kevin McBride.
