It actually is used! But it's set as an environment variable by the VS Code extension rather than exposed as an LSP setting. I'm not 100% sure why, but it's how the VS Code extension template is setup. The relevant code in the LSP:

def log_error(message: str) -> None:
    LSP_SERVER.show_message_log(message, MessageType.Error)
    if os.getenv("LS_SHOW_NOTIFICATION", "off") in ["onError", "onWarning", "always"]:
        LSP_SERVER.show_message(message, MessageType.Error)


def log_warning(message: str) -> None:
    LSP_SERVER.show_message_log(message, MessageType.Warning)
    if os.getenv("LS_SHOW_NOTIFICATION", "off") in ["onWarning", "always"]:
        LSP_SERVER.show_message(message, MessageType.Warning)


def log_always(message: str) -> None:
    LSP_SERVER.show_message_log(message, MessageType.Info)
    if os.getenv("LS_SHOW_NOTIFICATION", "off") in ["always"]:
        LSP_SERVER.show_message(message, MessageType.Info)

Ah, I see.
