Oil pump nightmare 04 LR2 4.6
That's not a nightmare, just a failure. Replace it and you're done. Or is there something else you're not telling or showing us? If you scroll down to view related threads there is at least one instance of the same failure on a Discovery.
Bummer. But in all honesty, unless the motor was at idle or very close to it you might have scuffed the bearings a bit... it's hard to catch that fast enough. Synthetic oil would certainly have helped there, as would maybe some engine oil wear additives.
I. Only run full synthetic, as well as a zinc additive. But yes I was on the freeway. An with an idiot light it's usually to late when you see the light. Would it be wise to pull a rod cap an look at a bearing as well as a main cap to look at a main bearing while pan is off

You'd also want to look at how the oil flows in the galleries, hopefully the manual depicts that, would be best to check the rod and main furthest downstream.
Some slight visible wear can be normal on bearings, they may not be mirror-smooth and that might be OK. Any sign of copper showing through is bad. You can google it.
If it were me I'd probably talk to my indie mechanic, see what he thinks. Probably have him do it... if won't touch it, that's a hint.
Synth + zinc sounds promising, that might hold up for a couple seconds.

Maybe. Need to check out the service manual and look at bolt torque patterns, see if it's just a simple on/off or if you have to re-torque all the other mains. Also see if bolts can be re-used. Modern engines are pretty finely engineered, so those details would matter for bottom-end stuff.

Here is what's left of the oil pump after I took the front cover off
believe it or not, there was not 1 trace of any metal in the motor. I even cut open the filter an checked.
