The folding is available by [CodeMirror](https://codemirror.net/doc/manual.html#config), which can be modified via the _Advanced Settings Editor \> Text Editor_, and might get you closer to what you’re looking for:

```json
{
    "editorConfig": {
        "codeFolding": true
    }
}

```

I don’t know of a pithy way to get indentation characters to show in codemirror, but there might be something out there that could be wrapped into…

As for LSP-in-lab: there’s [jupyterlab-lsp](https://pypi.org/project/jupyterlab-lsp/) which knows how to work with [python-lsp-server](https://pypi.org/project/python-lsp-server). There’s also a [longer discussion](https://discourse.jupyter.org/t/any-jupyterlab-extension-support-py-script-editor-and-project-management/10451/6).
