I’m afraid the short answer is no, or at the very least “I doubt it”.
The longer answer is: I don’t know what parts of Libresprite’s API are compatible with Aseprite’s API, if any. This extension also relies on Aseprite’s CLI to handle Lospec’s “Open In App” links, so that feature would almost certainly not work in Libresprite.
