Charitable gift annuities don't have the result you describe. For starters, they're only partially deductible, and you have to pay taxes on income earned by the annuity. In effect, a lottery winner would pay taxes twice: first on winning the income, and then when receiving money from the annuity (because a partial charitable deduction wouldn't offset the annuity income and for a gift in the millions would be capped anyway).

Really? They have exactly the results I described. In what way do they differ from what I wrote?
Charitable Gift Annuities are not theoretical, despite you having gone from protestations that Universities would go out of business for engaging in them, to now saying that I wrote things I didn't.
P.S. A deferred annuity for a lottery is an entirely different product from a charitable gift annuity.
