any company will let you expense a few hundred dollars for a tool you use literally every day many hours a day. if you’re having trouble they are not good to work for or you’re asking the wrong way

I dunno I've been in plenty of situations where a department head will literally beg me to buy things so they can reach the same budget spend as last year so their budget isn't slashed (DoD), and have seen the same situation in VC-backed startups looking to come up with tax write offs. Businesses for the most part love spending money and would rather do that than pay taxes, which is definitely a problem with corporate society these days.

In most cases you cannot use personal licence on a company hardware. JetBrains also have separation between individual licences and organization licences.

if a company wont pay for an IDE for there developers then I certainly won't be paying for it out of my pocket.

if they can't justify paying ~$100 for my ide of choice, then they are costing them selves far more in lost productivity, and that's not my problem.
