I think they're making that grammatical choice deliberately because they're modifying the language to better support TensorFlow integration, as opposed to just providing bindings for it.

It depends on what you're focussing on. If I've got a MySQL backend and using different languages, I may be looking for a MySQL driver for Java, or a MySQL driver for PHP. If I've got PHP backend and am moving from MySQL to PostgreSQL, I'm going to be looking for a PHP driver for PostgreSQL. Since it's the TensorFlow community, I trust they named it like they wanted. I can see it either way.

It's using Swift to create a TensorFlow (or XLA) graph which can be evaluated on a TPU. From that point of view, the name makes sense.

It comes off rather arrogant, doesn't it? Not unlike Windows Subsystems for Linux, which is named exactly backwards.
