You've pretty much explained it with your mention of the difference in the books. The Hobbit certainly has an overall much lighter tone than LOTR
. The dialogue and names of the Hobbit trolls were regretted by Tolkien, who had not the understanding of the world he'd created in those days.
Tom, Bert, and Bill were probably not much different fundamentally from the Moria trolls. They were likely followers of Sauron, and would probably have killed any Men, Elves, or Dwarves they could, whether they were hungry or not. I'm not sure, really, if Tom, Bert, and Bill were cave trolls. Strider just refers to them as trolls when he sees them, whereas Gandalf specifies cave trolls in Moria.
My first time using the Outlook-type italics and whatnot. Wonder if it worked?
