Firstly, welcome to FT! I hope you find the forum welcoming and useful.

It sounds like there might not be a straight forward answer - Bali is somewhere visited by people from some heavy smoking countries. If your neighbours are particularly active smokers, perhaps you could be moved to another Villa? I would not expect this from a Marriott where you should really just live with policies, but at an RC it doesn’t seem unreasonable for them to try to move things around a bit.

So asked the manager to move us, at first he offered us a room on the 2nd floor (we are currently on the top floor), we said we want the same view so then we were offered a pavilion villa again with no view so we declined. Picky? Yes. But we value the view from our balcony the most.

Also so when talking about the smoking policy to the on duty manager, he said and I quote ‘no one has ever complained about this, you are the first’. I think not.

I understand your point. I submitted to looking at the beautiful Balinese ocean from behind the balcony doors instead to avoid the smoke. IMO it’s sad to come to such a picturesque place and not have a good view!

I suggested smoking customers and non smoking customers be put in separate buildings for the junior suites. Probably will hear a sorry back from upper management and an offer of a couple hundred Marriott points

dont know what room had originally booked but a pavilion villa here seems like a big upgrade with private pool. The hotel appears to have tried to work it out.

It would help to know what category room was booked by the OP, what category room was given at check in (and currently occupied), and what room categories were offered for a switch. While I generally object to taking a downgrade if there's a problem with my room, I realize that the higher category room cannot necessarily be better in every dimension. I'd probably be happy to take a much higher category room without smoking, especially since the OP had already had the opportunity to enjoy the view and presumably can do so from elsewhere in the property, such as in restaurants and bars.
If the OP rejects two offers to move to other rooms without smoking, I'm not sure what else the hotel can do or should be expected to do. Moving away from the smoke is the obvious solution and I'm not sure that any further customer service gesture is warranted in this case,

booked into sawangan junior suite, same room type given at check in but with high floor ocean view. Offered sawangan with lagoon access at first then pavilion villa afterwards.

The point is that there are no non-smoking rooms/ villas at all, (you can smoke on every balcony and outside every villa). I am fully aware that the rooms offered to us are substantially more than our original room however the original problem lies within the management of the hotel, I am not complaining that the compensation so far is inadequate. My point is you cannot move away from the smoke because it is everywhere.

Another example would be the smoking area outside the breakfast restaurant is pointless because the smoke drifts towards all the non smoking tables anyway. (But that is another discussion for another day)

sounds like your asthma is not a big deal if you turned down two different rooms. Is the smoke
leaking into your room when the windows/doors are closed?
