I wouldn't say so, litecoin markets itself as "the silver to bitcoin's gold" for being lighter cheaper faster etc, it did add a "privacy layer" called mweb but it works better for scaling than privacy, there is still a tx graph that can be observed and archived, etc, but that aside it's still in all major exchanges and hasn't been targeted for its "privacy capabilites" cause it's not that good, kinda like bitcoin's LN, it is a "privacy layer" but also doesn't make it a privacy coin
