On jet airliners the main landing gear should arrive first and absorb nearly all of the energy on touchdown; after this the nosegear should have no problem absorbing any energy when it is 'flown' on to the runway. Even if the nosewheel appears to bounce a little I would doubt that this would cause any significant damage. (Remember that the nose gear is built to be tough enough to withstand some fairly aggressive towing forces)
There have been occasions when the aircraft has touched down on the nosewheel before the main gear. (Nearly always as a result of poor handling) In this instance it is very likely that significant damage will occur to the nosegear and the surrounding structure.
Back in the 1970's I remember a very sad looking B.707 sitting in the hangar that had suffered in exactly this way; the bottom of the fuselage nose was only about 6 inches from the hangar floor and the nose leg had been forced up into the surrounding structure. In addition, by the way, a pod had been badly scraped. Perhaps an interview without tea & biccies for all concerned.
I did however once witness a BAE146 arrive at LGW 26L, touchdown nosewheel first, and then continue to 'wheelbarrow' down the runway on the nosegear only for about 300 metres. When we lined up we could see it taxing back down the parallel in what seemed like a fairly normal manner. We asked the tower to pass on what we had seen at the time, but the BAE 146 remained silent.
Hope this helps.
