No, you said the following:

Which is demonstratively false.

The CAS is telling you that there is no standard form for:

ℒ[1/t]

WolframAlpha agrees.

My bad I apologize, don't know why I typed in 1/t ! Prime certainly can do t.

Anyone one reading this thread, it's a false alarm, sorry for the confusion.
