I had a similar predicament with a brand-new Kubota UTV. The first time I checked the oil I found that they had overfilled it by a lot. So I got out the oil suctioner that I use on our push mower, which doesn't have a drain plug. I inserted it into the dipstick tube and sucked some oil out. But when I tried to remove the soft plastic tube, it got snagged and the end sliced off (I suspect there was a sharp burr on the lower end of the steel dipstick tube). I called the dealer in a panic, but both the salesman and the service manager said I should just leave it in there; that it would just sit in the bottom of the oil pan, and that baffles would prevent it from finding its way into moving parts. Looking at drawings of the engine confirmed that it shouldn't be able to go anywhere. I hope I'll be able to grab it when I do the first oil change, but after 14 hours, so far so good. Not being familiar with your engine, I'm not recommending this, but it could be worth investigating whether the best course of action might be to do nothing.
