I have tried numerous times to get a z/OS LPAR and an AIX VM without any luck. It's a complete mystery to me.

IBM probably doesn't make mainframe LPARs available over the internet because the cost of the LPAR would be cost prohibitive to any potential customer. On the other hand, a z/VM guest or an LPAR on POWER should absolutely be an option.

They do. A z/OS with a single CPU and 4GB of RAM costs around $2000/month. It's a bit of a hassle, as you need to connect to its VPN and will need to add a public network gateway for your machine to see the world, but that's it. It could, of course, be just a tiny slice of z/OS running under a larger LPAR, but IIRC, LPARs can get really small. You can go as far as 16 vCPUs and 128GB of RAM for roughly $30K/month.
Last time I tried I had issues with the VPN and couldn't connect to it. I'll try again later. Another good thing about IBM cloud is that they embrace Terraform and you can download templates for just about everything they offer.
