I'm really concerned that by not putting some silicone on the o-rings they are leaking. Doing the job again would no doubt be a lot faster since I don't have to examine everything before I remove it and/or spend so much time thinking things through before I put them back together. Been there done that...and that's why mechanics who've done these jobs a dozen times can get it done so quick. Hell, it took me about three 6 hour segments to do the job that the dealer only charges about 8 hours to do.

If you don't lubricate those O–rings there's just a chance that by pushing the pipes in you would push O-rings from their grooves further into accumulator.
While I was dealing with a multiple leaks which appeared after VP gasket and rear collector gaskets replacement,I found the way to release a bit of pressure after each drive,so if it leaked only because of excessive pressure which pushes through a weaker point.Undo the expansion tank cap briefly and tighten it up.
I saved a lot of coolant by doing that.
Another thing to consider is....did you refill the coolant to correct level? Was your expansion tank cap replaced.
If the level is too high and a cap isn't working properly at releasing the excess pressure,pressure is gonna escape through some other spot.And probably could damage one of the hoses or so on...there are many plastic spots etc.
