I have a hard time believing river water would flow through Livingston Parish with the levee failure event you described in the OP.
Once the water gets outside the natural levees, it pretty much has to. All that land East of the Mississippi in the Baton Rouge area drains to the Amite and Comite, not the Mississippi. Maybe if it's far enough South, then it would all flow through just Ascension?

If it keeps on raining, levee’s going to break

After looking at google maps, I change my mind. I think water would flow from Bayou Manchac to the Amite.. and Livingston Parish would be susceptible to flooding around Port Vincent and south.. and then maybe backwater flooding for the areas around Lake Maurepas.
I was thinking about the I-12 corridor, which I do think would remain dry.

How much would it spread out before shoring up the levee and stopping the flow?
They would not be able to stop the flow. Been tried up north once. Heck, they couldn't stop the water flow from the level breaks from Katrina.

Depending on where this break occurs of course, it would fill up the Brightside/Gardere/Bluebonnet areas south of Highland Road, hit Bayou Manchac, fill up Spanish Lake, and then flow toward the Amite river flooding Ascension.
All the while leaving any rainfall over the area with no where to go. Would make 2016 look pretty mild comparatively.

Jesus Christ I didn't think of that aspect.

Hypothetical - Say the Mississippi River is @ 43' and the levee breaks in BR
Before te levee system there was a river that flowed into the Mississippi just south of baton rouge, which is now part of the Bayou Manchac/Alligator Bayou system. a break south of the BR (L'auberge area) would possibly result in the river flowing that old pathway to the amite....

River reroutes through Bayou Manchac and Lake Maurepas becomes the new mouth of the river.
Port Vincent becomes the new New Orleans.

I would bet more of Livingston than your estimate would flood. With the Mississippi River flowing through various outlets, Bayou Manchac being one of them, the river would then empty into the Amite River. The Amite then swells to biblical proportions, spilling into surrounding areas of Ascension and Livingston. The Amite upstream from Port Vincent then has nowhere to go, resulting in it backing up big time. Then there are the various canals, streams, and bayous throughout Livingston that flow into the Amite River.
Then there's the thing Duke pointed out -- any rainfall that occurs would have NOWHERE to go. Imagine what happens when one of those springtime fronts comes through and stalls, dropping 5-8 inches of rain over the whole area.
Bottom line: the entire BR metro area would be absolutely decimated with flooding.

Nope.

Yeah, you'd have backflow flooding all up the Amite like in 2016.

You wouldn't even need a stalled system. Just the normal parade of systems dropping an inch or two at a time spells trouble. Yeah though, spring wouldn't be ideal (as if any time would be good) for your doomsday scenario.

that's a lot of water.. wouldn't it find places in every direction where the elevation is lower that 43'?

Yep, and backwater floods the rest of Ascension. New River would destroy Gonzales. St. Amant would mercifully be wiped off the map.

Yeah but all of it headed to lake maurepas eventually, through all the waterways that drain the area.

Bayou Manchac and the Amite are not deep enough for the Mississippi River to naturally reroute itself through. Once the river goes down, it resumes it's normal route because even though the flow through it would be tremendous, no way it would be enough to carve it deep enough to stay there.
If the Old River Control Structure ever failed, then yes, the river almost 100% reroutes through the Atchafalaya River since it's deep enough already to be carved deep enough for the Mississippi River to stay there.
***I am only guessing here.
