I only read about 2% of what you said, and I didn't even see a question from you, but unless the GoFundMe campaign is giving services or products to those who pay the money, the people giving the money are giving Gifts.

As such, it is non-taxable to the person receiving the money.  The person receiving the money can do whatever they want with it, including donating it to a charity.

The people giving the original Gifts can NOT get a tax deduction because they are not giving it to a charity.  But the receiver may be eligible for a charitable contribution if he gives it to a charity.

If a 1099-K comes, you can ignore it and respond to the IRS notice when it comes.  Or you can try and avoid a notice by reporting it and then 'backing it out'.
