As others pointed out, the IRS does not want single member LLC's (taxed as a sole proprietorship) to be paid under an EIN. That doesn't mean an LLC shouldn't have an EIN, only that if you are to receive a 1099-NEC, it should be under your Social Security #.
I had to have an EIN to open a business checking account, I wanted an EIN to use on 1099's that I issued.
