I think there is some connection, but this is the connection which is yet to be revealed. I can speculate on it a bit. For example, as far as I know, in the Last Movie novellisation, it's mentioned that Tenseigan can accumulate nature energy. So, if we assume that Toneri was able to use nature energy via his Tenseigan eyes, then it's possible that his chakra mode was something akin to a Sage Mode. And since we know for sure that Mitsuki's chakra shroud is an actual SM (or Sage Transformation at least), it could at least explain the similarities with Toneri's mode.
