What happens to old bitcoin addresses? I've read that they never get destroyed, but do they get reassigned?
Bitcoin addresses are not reused or reassigned to anybody under any circumstances.
The story is I sent some bitcoin to an exchange using an address I've used with them before, but then found out that they had just retired/stopped using that address.

Bitcoin addresses are essentially just large random numbers. So there's nothing to destroy or reassign - it's just a number.
When you "create" a new address, what you're really doing is just picking two random numbers (that are cryptographically linked to each other) called a "private key" and a "public key". The public key is ...

Looking at the address you provided in a block explorer(OXT Explorer)
12aAEnfc6192cm4KLfV5eY13jYRqy684Ym
it seems your exchange has been reusing that address quite a bit since December to now and has not really cut down on using it. I do not think they have retired the address and it is definitely still under their control.
Is there an official network ...

No, it's not known, and information like that generally won't be publicly released. Bitcoin addresses aren't generally publicly associated with the real-life identities of their owners.
I would expect a company like Tesla to have the bulk of their cryptocurrency assets stored in institutional custody regardless, for liability and regulatory reasons.

I think these is only one answer to this question: ask whomever gave you the xpub.
Xpubs define series of keys, but there isn't any implicit contract or understanding about how that should be converted into addresses. The specific index positions to use is one question, but there are others, like what type of address/script to use (P2PKH, P2WPKH, ...). All ...

would it be safest to double check
Yes but the difference in safety, although not exactly zero, is approximately zero.
is it true that when there is a collision of address, both that person's private key and mine can move this bitcoin amount to else where
Yes.
Statistically that will not happen in any timespan you or I can properly comprehend. See related ...

Electrum allow you to create HD wallets that use seed to generate a near infinite amount of addresses.
All bitcoin addresses are public so it is better to use different addresses each time you receive coins for privacy reasons

If I get your code and use "e41b45e722251672c01a28e4fada590471fea09f90d13b143033ed3a1107ef49" as secret hex value AKA secret private key... then I get result: "12sF1DbBbPaoNYrs28Qm7waiCcAVoF93Nn" which is uncompressed public address.
Check my script, it is more extended, but with a copule of imports for an educational point of view, to ...

Typically there's a seed which is displayed as a sequence of 12-24 words that is used to derive addresses/private keys in different chains. Different coins use different derivation paths which are hardcoded in the wallet so even if two coins use the same address format the generated addresses will be different.

No, you should not reuse addresses/treat them as a "mini-account". You should create a new one for every transaction and not re-use old addresses.
Your wallet software will generally handle this automatically for you -- just remember to request a new receive address each time you receive new bitcoin, and it should give you a new address that you ...
