entwine, coil around, get caught in
絡 centers on threads or strands wrapping around something, creating entanglement or involvement. The core idea is entwining or coiling around, which naturally extends to getting caught in a situation.
絡 combines 糸 (thread) with 各, which likely contributes the sound and the idea of separate strands coming together or wrapping around.
Thread 糸 wraps around each 各 thing, coiling and entwining until everything is caught together.
For ラク, imagine a rack of threads that easily entangle you: rack -> ラク, and the threads coil around.
