According to our current excavation, it can be inferred that Lei Lei was not invented by the Yellow Emperor. A drilling stone axe was found in Banpo civilization site, and a bone was found in Hemudu civilization site. These are all used in agriculture in Lei Lei. There are different Lei Lei in different times and regions, which shows that it was not invented by one person, but the crystallization of the wisdom of the ancestors of the Chinese nation.

The reason why it was invented by the Yellow Emperor may be that the Yellow Emperor transformed the thunder, made obvious progress, or had the embryonic form of modern thunder. Or simply sing a hymn to show how great the Yellow Emperor is.

The above is just my own analysis.
