If you think that investing in index funds is sure to lead to the best outcome, why not give each recipient enough money so that they can invest in index funds? Or otherwise arrange it so that the recipients own and control the capital? Is it plausible to think that the donor owning the capital for 100 years is preferable to the recipient owning the capital for 100 years?
Option A: Put money in an index fund, let it grow, spend it in 100 years
Option B: give it to people who will spend some of it now, invest some, pass on some to their children, who will in turn spend some of it, invest some of it, and pass it onto their children, leaving some for their grandchildren to spend in 100 years.
Option A leads to a bigger counterfactual increase in spending-100-years-from-now which is what we care about in this (admittedly contrived) example

Well in this case the recipient does not currently exist and I cannot give them any money.
Give it to their ancestors.
see my previous comment:
Giving it to their ancestors is choosing option B
If by Option B you meant that the recipients would invest most or all of the cash transfers in index funds, why is Option A preferable?
