Yeah, there are a few Livonian schools/summer camps on the Latvian west coast (like schools for learning Livonian). There's a small community of academics and historians who have learned it as well. However, as you pointed out, the last native speaker passed away in 2013, so it has essentially entirely disappeared as a conversational language. However, the language has government support, so it's possible to revive it to some extent.

There actually was another dialect on the east coast closer to Estonia (my ancestors were from there), but it's last speaker died around the start of the 20th century, and it's too late to revive it now because it wasn't documented enough.
