Oy... Those are actually a bit rare (assuming it's an LM3886 or similar). TI doesn't make that package style anymore.
The odd numbered pins may be easier. You'll want to bend the leads maybe a millimetre away from the package. I think the even numbered pins would be worse as you'll be straightening out the bend, thereby risking weakening the pin. Why not just use the chip as is and put it on an aluminum L-bracket connecting to a heat sink?

Thanks Tom for the reply. Also thanks for correcting me. I meant confused the odd/even pins.
I thought of using an L brackets but my OCD won't let me lol
What is wrong with using a small PC board or perfboard with a connecting cable?
It's been done commercially with no problems.

Sounds like a good reason to deal with the OCD... 🙂
National Semiconductor used to ... before the acquisition by TI.

"Could" yes but if one is willing to design such a contraption decoupling might also be forgotten.
In a Sony subwoofer, the 3886 has its own tiny board with a cable to the mainboard. (including two components.
No big deal, not worth even fussing over.

nothing wrong with L-brackets. just my other chips are "upright". With my OCD, it would bother --me--.
It is not a high level of designing to omit local onboard decoupling is it? Category "it works" for consumer use.
It is like people that are afraid of the dentist, these usually are the worst with tooth brushing.
A solution could be to use the normal version of the chip. If you continu with bending pins a new OCD will occur. Pins that are bent wil be mechanically a lot weaker than before. A L-bracket is superior for ICs that are meant to be mounted on L-brackets. It is like trying to bend bananas straight.
