Splashing is okay pre-fermentation, as in while transferring to the fermenter, which is what I assume you mean. In fact, it will help to aerate/oxygenate the wort, which is good for your little yeastie buddies.
Boiling the wort will just drive off o2 anyway. so chilling it down & splashing/aerating before pitching yeast is fine.
There's a continuing debate about the effects, if any, of "hot wort aeration" causing off-flavors and the extent to which one must splash to cause the problem.
I tend to err on the side of caution and try to not splash the hot wort around. Cold wort (under 80*F) aeration, on the other hand, is a good thing.
Splashing after fermentation has begun leads to oxygenation (which is bad). No debate about that one.

I really screwed up my last batch. Got a stuck sparge and in trying to fix it and transferring the wort between buckets/pots, it got splashed to all hell and abused like a red headed step child. If this batch turns ok, I'm going to lean towards hot side aeration not being an issue...

I just did this with my last batch.
I had no way to measure volume in brewpot, so when the sparge stuck I had no idea how much wort I had.
So I had to dump into measuring bucket. All while hot.
I am too am hoping HSA is a myth.
I think it takes a goodly amount of wort abuse before HSA (Hot Side Aeration) becomes a problem ime so far.
What I did was a batch of BIAB and pulled my grain bag our if the sparge pot (batch sparge ) and set it on top of a cake drying rack and poured my wort back thru the grain bag to filter it . So it all splashed down into the pot from 10 inches high at the highest. Then began my boil
I put mu BIAB in a SS collander on top of the BK/MT to sparge. It starts out at about the same height,& no problems thus far.
Nearly all of us splash our wort pre-boil. We are either doing a vorlauf or sparging our BIAB.
Don't worry.
