An atomic swap is not instant by design. Each side has to publish a transaction and wait for the other chain to confirm it, so the time it takes is set mostly by the block spacing of the two chains involved rather than by anything either party does.

at the legacy address for this key
this party's legacy and segwit LTC-segwit addresses have no transactions at all, so they funded from an address this key does not derive (usual with a wallet that derives fresh addresses); matching by amount cannot reach it
No flags are stored against this swap. Flags are written while a swap sits inside a live pricing window, so on an older swap their absence means it was never assessed rather than that it was assessed and found clean.
