I have a Phil's Philler. The hole at the top is closed when the main
valve opens. There are no apparent bubbles at the exit of the filler
(no bubbles floating to the surface) during filling. The filler is
designed very well and does a great job.

This is the primary source of oxidation in bottles, followed by
excessive head space. The spray creates great turbulence in the
presence of air and can oxidize the beer. You may as well pour
an ounce of beer in the bottle and shake it up before filling the
remainder. If you could purge your bottles with CO2 before filling
with beer, this problem would be eliminated, but that's obviously
too much work.

I disagree; a spring clamp on the siphon hose can work just as well
for controlling/stopping the flow and produces no splashing or spraying.
