My understanding is that wasmtime-wasi library can be used to call wasi-0.2 api's in a project that is to be complied to WASI. Specifically I want to make use of the Socket api, which tokio doesn't seem to have implemented. If this is not the case, what options do I have .

You are probably looking for the wasi crate. The wasmtime-wasi crate contains the host implementation of wasi when using wasmtime. It is never used as part of your wasm module. The guest (wasm module) side bindings are provided by the wasi crate.
