Lab leak is one thing, "deliberately created and escaped" is a different story.
It depends on personal interpretations of "deliberately created". To wit, virology labs will deliberately breed up more virulent strains of viruses in order to study their effects.
"deliberately (created and escaped)" is very implausible yes. "(deliberately created) and escaped" not so much though.
