Should I use a multi-sig wallet to avoid private key collision paranoia?

Hi everyone, please don't hate. I know this might sound like extreme paranoia, but I need some peace of mind.
I've been feeling anxious about the remote possibility of someone randomly stumbling upon my private key using websites like keys.lol.

I fully understand the math behind it and know it is practically impossible, but it is not mathematically impossible.

Regarding the math, Bitcoin addresses (like P2WPKH) use RIPEMD-160, which gives a collision probability of 1/2^{160}. If I use a 2-of-2 multi-sig setup (P2WSH), an attacker would need to guess two independent keys, theoretically pushing the security margin way further (closer to 1/2^{320}).

I already know how to use Sparrow Wallet and manage XPUBs.

Am I being way too paranoid here?

Summary: For a long-term hodler with high anxiety about collisions, should I stick to a standard single-sig (P2WPKH) or move to a multi-sig (P2WSH)?
