Subject: Re: Buying Long Dated Calls
In these DITM LEAPS there is no or little open interest, so it is unlikely that there is any public investor trying to sell the calls.

I'm not sure that this is solid reasoning...if someone decides to write that option, it shows up as as "sell", and the contract never before existed. I can't think of any reason to think that the bid or the ask is more likely to be a market maker or bot. If I want to know, especially for the thinly traded things, the quantity at the bid and ask is the best bet. Generally when I'm looking at the trade-offs I just graph the rates and ignore the outliers.
