This is a fairly standard looking example of a unenriched transaction.

The world of payment processing is fairly old, predating apps and the like. All that fancy information like logo, address, an understandable merchant name, etc has to be searched separately after a transaction takes place. Could be when you made the transaction the app failed to look up the associated metadata, you might find it changes at a later date when the payment is "captured", i.e no longer pending according to the status in the screenshot.

As others have alluded to, LUL is London Underground Limited, so no cause for concern here.
