You are right that the US doesn’t have a monopoly on this, but they are almost certainly the front runner. There are plenty of European conservatives that donate to these “causes” and we can’t forget the Catholic church that has recently compared “gender ideology” to nuclear war. Russia has also been pushing conservative and anti LGBT views, though I’m not sure how much they are involved in Africa. I’m sure there are plenty of others that I’m leaving out.

These countries have not had the most reliable reporting on topics like these, so data quality/availability is a likely reason for their absence.

Religious fundamentalism is strongly correlated with anti LGBT sentiment (at least with Abrahamic religions), so it is fair to assume that these countries are probably not very good. It is also worth noting that most of them are like they are due to meddling (or outright coups) by western nations. Iran was fairly progressive for its day before the CIA overthrew their democratically elected government.

My guess is the billions that the US has spent to export evangelical bigotry in Africa.
