Anyone have guesses about how a transiting primordial black hole would effect a Sun like star? Paper is about tidal forces inducing supernova in white dwarfs. For that matter how might it effect sea tides?

Most likely minimal? The mass is low.

I am, however, reminded that the orbit of the asteroid Juno (~250km diameter) permanently changed in 1839 without an obvious cause.

		Note that the orbital perturbation of Juno in 1839 was of rather low magnitude, and could have been caused by an asteroid as small as ~1km diameter. Based on current models, there are potentially more than a million rocks that big in the belt still undiscovered.

		Wouldn't low-mass primordial black holes have evaporated by now?

For the latter, you mught enjoy Greg Egan's "Perihelion Summer".

Picturing the crust of the earth being pulled off like an orange peel. But maybe seen too much scifi so it's probably a lot more boring :/

		I think at the energy scales we're talking about, everything involved would basically act like a fluid.

We have constraints that primordial black holes must be less than the size of a large asteroid. They would be gravitationally insignificant to the Earth unless they actually passed through it.

I also don't think it would really be detectable in the Sun. Perhaps there would be some transient astroseismology signature.

		Perhaps you meant to read the https://news.ycombinator.com/newsguidelines.html about comments being kind, not snarky, and substantive.
