Update LLVM Version to 19

[Bishoywadea]

🐛 Bug Report

The project is currently running on LLVM 11. We need to upgrade it to LLVM 14 to ensure compatibility with the latest toolchains. Attached are two images comparing the results between LLVM 11 and LLVM 14. The goal is to confirm that the code runs correctly on LLVM 14

Expected Behavior

The project should properly support LLVM 14 without any issues.

Current Behavior

See the attached images for the current behavior:

Possible Solution

• Update the code to use LLVM 19.

Detailed Description

Behavior when installing LLVM 11 (Removed from Homebrew)

Behavior when installing LLVM 14 (Potential Compatibility Issues)

I think it will be better if we update it to 19. Specially because we have it in bookworm and trixie: https://packages.debian.org/search?keywords=clang-19-examples

Also, in homebrew:
