I'm a FL resident employed by a FL based company doing work in NC. Who should pay NC state tax, the worker, the company or both? I assume since I'm not a resident of NC I will be able to file to have these deductions returned at the end of the year.

Any wages you earn while physically present in NC are taxed by NC. You pay this - not the company. And no - there is nothing to file to get those taxes returned (though of course you can deduct these taxes on your federal tax return).

So I have to get a D400 form & file like NC residents since I made over 15k in the month I worked there?

Yes, but you complete the form as a non-resident. The form requires you to report all your income for the year and calculates a preliminary tax based on that full amount, but then multiplies by a percentage representing the portion of your total income that is from NC sources. The result is you pay taxes to NC only on your NC-based income, but using a tax bracket that is determined by your total income.
