There is a large section of our front lawn that has this green weed that was unaffected when I used Lebanon Broadleaf Weed Killer about 3 weeks ago.

I need to figure out how to kill this stuff so I probably need to figure out what it is first. Thanks

It looks mostly like purslane. Does it have red stems and fleshy leaves?

I googled the weed you mentioned, also called Black medic and the photos look exactly like what's growing on our front lawn. It also mentioned it's very common in compacted clay soils which is exactly what we have where this is growing.

Now I need to figure out how to get rid of it. Thanks so much for your response!!

OK, that is definitely not purslane. How tall does the stuff grow? Does it flower at all?

Are you sure you want to get rid of it? It is a nitrogen fixer which means it converts nitrogen in the air to fertilizer in the soil. But if you do want to eliminate it in a grass lawn just use one of the auxin herbicides that has 2,4-D, dicamba or similar herbicides in the mix.

I looked it up online and the best listed product was Turflon Ester and I ordered it from Amazon since it did not seem to be locally available.

It's less than 3 inches in height and there are some white flowers but not all over. It almost looks like clover.

That's because they're related. Both medicago and clover are part of the Favaceae, or bean family.

What that medicago is telling you is that you have nitrogen-deficient soil. If you don't fix that, your lawn will never thrive, and you will always be fending off non-grass plants in your lawn.
