Ent isn't sure Lobelia
Sackville-Baggins had heard much about natural resistance to
evil.
And given the writing, Ent wouldn't characterize the situation with the
hobbits as "an easy time resisting
the ring" probably, either - though of course others may
We do know of two Hobbits that had a pretty strong resistance to it, and a third one that - though using it pretty much at will - didn't succumb to its evil, though he too was adversely impacted by it and only let it go under coercion.
Smeagol, considered by many to be most likely an ancestor of Hobbits, certainly had no resistance... neither did his brother Deagol.
Ent concludes the resistance isn't a factor of the
race, but the particular individuals involved.
We can look to
Galadriel, and
Faramir, for others who had, as individuals, similar resistance to its pull. And certainly to
Gandalf. Though he was almost certainly
Maia, nonetheless many Maia were turned to evil by
Melkor.
No, Ent can't see the Holbytla as having any special resistance due to their race or especial 'magical powers'. (Nor is he certain they are ever attributed with any special 'magical power' other than their ability to vanish quite quickly when the bigger folk came blundering about.)
So those are Ent's thoughts. Feel free to disagree. We must not be hasty.
