No. 'The Lord of the Rings' was not a Cold War novel. It was written long before the Cold War era, with Tolkien starting to write it in the 1930s. Its themes are mainly centered around good vs. evil, heroism, and the power of friendship, which are more in line with classic fantasy and moral concepts rather than being related to the political and ideological struggles of the Cold War.
No. Tolkien began writing LOTR in the 1930s and was influenced by his study of mythology, his experiences in World War I, and his own moral and religious beliefs. The Cold War started much later, and there is no evidence that Tolkien was thinking about Cold War politics when creating Middle - earth.

Well, in the Lotr story, there are female Dwarfs. Their existence is somewhat in the background. The Dwarfs were a race that was more often presented through their male counterparts in the story. But we know that they had a role in the continuation of the Dwarf race. They were likely involved in teaching the young Dwarfs, maintaining the traditions within the hidden mountain kingdoms, and also in some of the more domestic aspects like food preparation and the making of clothing and other items necessary for life in the Dwarven communities.

Well, you could do a lotr fanfic that focuses on the magic in Middle - earth. Maybe a story about a young wizard in training who stumbles upon an ancient and powerful spellbook. Or you could write about a fanfic where the orcs have a different origin story than what's in the original lore. Also, a fanfic set in a parallel Middle - earth where the Ring was never found and how the different races would have developed in that scenario.
One interesting Naruto LotR fanfiction could be where Naruto is transported to Middle - earth. He might use his ninja skills in unexpected ways against the orcs and other dark forces. For example, his shadow clone jutsu could be used to create diversions during battles.
