老糊涂 is a colloquial noun meaning 'a senile old person' or 'dotard'. It combines 老 (old) with 糊涂 (confused/muddled) and is used to describe an elderly person who is mentally unclear, often with a tone of mild disrespect or self-deprecating humor. The actual pronunciation is lǎo hútu, though the input pinyin shows lǎo hū (likely a data error). You can also use it as a predicate adjective (他老糊涂了 'he's become senile'), but the POS here is noun.
