Morphology
The meaning 'to inform us' follows directly from combining 'let' (allow) with 'us' (the speaker group) and 'know' (be aware of information) — i.e., 'allow us to know' → 'tell/inform us'. This is a frequent, compositional verb + object + verb pattern in English and is readily predictable for B1 learners who know the constituent words.
Etymology
The phrase let us know comes from three simple words: let meaning 'allow', us meaning the people speaking, and know meaning 'have information'. So it literally asks someone to allow information to reach the speakers, which is why it means 'inform or notify us'.
