A Toxic would be AIO cooled I think. For a blocked model for custom loops it should be an Atomic.
Sapphire did a limited run of a Toxic AIO of the RX 6950 XT but nothing they really want to do because of the warranties that they need to provide with AIO that's what I been told from Edward Crister their NA Rep.
But maybe it will change one day I don't know.

I still believe that a 300-400W card can still be aircooled just fine it's when people want their full tempered glass cases which provide such limited airflow things go bad even for WC.
I ran the Nomad test in 3DMark yesterday just to get the achievement "Catchy Time" but I also ended up getting the achievement "Cool under pressure" and I was l what my RX 9070 Pure stayed below 55c
I treated myself to a PowerColor 9070 XT for €728 ($792), which is (or should I say was) the MSRP in my country. After the first batch sold out, they raised the price to €865 ($940). The fake MSRP and price hikes from both AMD and Nvidia leave a bad taste in my mouth.
Frank Azor from AMD have said it was only the first supply batch of cards that was MSRP sadly because of AMD's discount on them but AMD will try to work with AIB partners to bring more MSRP models but problem is many expect more models than Sapphire Pulse, PowerColor Reaper and Gigabyte Gaming to be MSRP. I am not sure Asrock's Steel Legend series is a MSRP card.
Because you will never get a better card like Sapphire's Pure, Nitro+, Toxic and such same for PowerColor Hellhound and Red Devil, Asrock Taichi, Yeston Sakura models for MSRP because they are not built to be MSRP cards.
So if AIB partners was only allowed to make MSRP models we wouldn't see other cards like the models I listed above we would only see bad cards like Asus' Dual and MSI's Ventus cards which ain't good enough for higher end dies but can do well on entry and mid-range models.
