You're right, Lightning transactions are visible to routing nodes along the payment path. That's the tradeoff for speed and low fees. Privacy tools: route obfuscation (random paths), higher hop counts, mixing services, or coinjoins before moving onchain. If you need full transaction privacy, Lightning isn't the answer. Monero is. Lightning optimizes for different things: fast, cheap, censorship-resistant payments. Pick the tool that matches the threat model.
