@vcunat is tls-over-dns also vulnerable to dns amplification attacks?

I don't expect there's a real vulnerability. Even for plain TCP I don't think there's a way to redirect answers to someone else.
If there was, I'd rather attack http(s), as the amplification ratio there is orders of magnitude higher, and usually the cost to generate answers is also higher :-)
