Bristow are currently recruiting cadet pilots for their helicopter operations and they fund the training (except living costs), in the UK they fly to/from the oil rigs in the North Sea and also provide Search and Rescue capability.

Prior to the pandemic, Aer Lingus ran a fully sponsored pilot training programme from around 2015-2019, I have no idea if/when it will re-open.
The US currently has a very strong recruitment market though in the UK/Europe it doesn't look like a good time to start training to me. We have very high energy prices, increases in the cost of living and I wouldn't be surprised if we see a recession in the next 18 months. Essential living costs will take priority over holidays and now that businesses have become much more accustomed to remote working, I can see a lot of them very quickly cutting business travel to save costs.
