Should fix the typos with functions/types name here?

[joohhnnn]

I've noticed that in the codebase, there are numerous instances where "Literal" is mistakenly spelled as "Litteral." This typo appears in various function names and types, making it look a bit off.

I understand that changing function names can be tricky, so I wanted to check in and see how everyone feels about making such changes. If it's all good, I'm more than happy to help correct these spelling errors.
