Suggested changes:

def _load_split_file(
    self,
    basename: str,
    open_f: Optional[Callable[[str], BinaryIO]] = None,
) -> bytes:
    file: List[bytes] = []
    for i in range(0, 1000):
        item = f"{basename}.split{i}"
        if open_f is not None:
            try:
                f = open_f(item)
            except (FileNotFoundError, KeyError):
                if i:
                    break
                continue
            with f:
                file.append(f.read())
        elif self.fs.exists(item):
            with self.fs.open(item, "rb") as f:
                file.append(f.read())  # type: ignore
        elif i:
            break
    return b"".join(file)
