I thought you might be interested in the following link:

https://github.com/BojanStipic/minic-lsp

It's a Language Server implemented entirely in C, including its own implementation of LSP. Since it's a stable product, you might consider taking the LSP library to use it here (released under GPL-3.0.

Sadly, this C implementation of LSP is not mentioned among the SDKs listed in the official LSP website, and there are no other pure C implementation of LSP that I came across (although there is a C usable SDKs, written in C++).
