I'm not sure there were ever consumer TLC SSDs that didn't use SLC caching (except for a handful that use MLC caching). SLC caching was starting to show up even in some MLC drives when the market was transitioning from MLC to TLC, and now there are even some enterprise drives that use SLC caching.

See I wanted to say "every" but I just know there exists some crap slow drive without one that survives because it is technically an "S S D".
Even Samsung's last MLC drives (970 Pro?) had SLC write caches. Otherwise they'd just be giving up a benchmark.
Enterprise is a whole different game tho, as the value of an SLC cache is inversely proportional to the write duty cycle...
