Regarding your points:

- LTE is supported since 2017: check this article (by using a translator) but some SIM cards may never have seen LTE. Then you need to contact their customer support. With Telefónica all secondary prepaid brands support LTE too (where available) and VoLTE.

- Netzclub is a brand of Telefónica Germany. ayyildiz is a brand of Telefónica Germany too (through the now defunced Eplus-Service GmbH), that Telefónica bought a few years ago. All registration of Telefónicas or o2's SIM cards are very similar as they use the same ways (o2 shops, some resellers too, Video-Ident through a video chat and PostIdent at some post offices or agencies). As Netzclub doesn't issue a country list which country works which way, the list of ayyildiz is shown instead.
