Orcs are. They got super violence charged by their gods. Pretty sure gnolls have or had something related to their gods in their background. Gnomes were given their magical abilities by their gods and taught by them how to hide their villages.
Other races get help from their gods. Just in different ways.
Not what I said. I said "no other race is
protected by their gods to this degree."
The orcs gods don't reach down and changes roads and grow thickets and waft away smoke for their people. They gave them a genetic calling, perhaps, but they are not nearly that active.
The Gnomes might have been given their illusion magic by their gods, but the gods don't come down and weave the illusions themselves, they gave their people a tool to use.
The Halfling Gods and Goddesses (according to your reading) are actively and constantly manipulating every aspect of the world to make sure that halflings are safe. Something no other god does.
Lore doesn't have to cover every common thing about a race. Do you really want a book of lore the size of War and Peace? A small, stealthy race would hide from an overwhelming force. This is just common sense and doesn't need to be in the lore. It's absence is not "poor lore writing."
We are told they are brave and will fight for their homes. You can say "but it is common sense that if the fight can't be won, they would run away and not die." But nothing tells us that, even being "stealthy" doesn't tell us that, since stealth can be used offensively.
You can keep "adding common sense" all you want, but that is what I did too. And I was told that when my conclusion came to "this doesn't work" that I was wrong, that the book held all the answers.
