Not sure what he did as the EGR has nothing to do with the fuel. So how it got from the injectors through the plenum into the TB and then flood the air filter is something that wouldn't be possible, not saying impossible, but it would be something really on purpose.

My suggestion is get it to a good shop or get a person who knows what they are doing to take a look at it.

And he may not have done it. Lol. But before he replaced the lines under the hood there was a small fuel leak from a line under the hood. after he replaced whatever he replaced the fuel poured out and soaked the air filter.

Not sure on how to even do it intentionally but here's a diagram on fuel #1, fuel return #2 and EVAP #3 lines which might help to take a look at.

PCV has nothing to do with fuel. There is no PCV hose on a Lesabre. The valve is inside the Upper Intake Manifold and vents the gases from the crankcase into the intake.
The connections 1 and 2 at the engine are where fuel could leak. Either your husband is doing something wrong or he's giving you misinformation (or both). Get a knowledgeable mechanic to look at it.

Can't offer much help as it seems there is some confusion on what was actually done, first it was the EGR and now it's PCV, so getting it to a qualified shop will be the best route.

If your husband is a prideful person, just from now on always assume it needs another opinion from someone first before acting or going down a rabbit hole. if you can, you can take pictures of your engine bay from a "few encompassing shots of the engine, and post them, and we can possibly tell whats north vs south and factory vs rigged but no guarantees either atm.Something tells me fuel pressure regulator had some issues and then vacuum harness, which is connected to the TB, is involved + either a backfire or gravity and the right slope of your car.

Fuel pressure regs this old are due for change
a car that stalled from sucking gas through the regulator would probs spit liquid gas back as it sputtered, which means if on your filter your MAF needs cleaning and your filter replacing and make sure rubber parts in intake are OK. if that sounds too much, it means youll need someeones involvement probably. but pictrues of your engine bay and situation could at least find any scary or simple solutions. We that is, we can help possibly and knowledge is power

There was a factory recall issued, concerning the fuel pressure regulator on that engine installed between '97 & 2000. It was a big problem and caused upper intakes to explode & catch on fire. I hope that is not the problem, but if it is, be careful and keep a fire extinguisher in the car. Good luck!
