We present the ALMA observations of CO isotopes and 1.3 mm continuum emissiontoward the N159E-Papillon Nebula in the Large Magellanic Cloud (LMC). Thespatial resolution is 0"25-0"28 (0.06-0.07 pc), which is a factor of 3 higherthan the previous ALMA observations in this region. The high resolution allowedus to resolve highly filamentary CO distributions with typical widths of$\sim$0.1 pc (full width half maximum) and line masses of a few 100 $M_{\odot}$pc$^{-1}$. The filaments (more than ten in number) show an outstandinghub-filament structure emanating from the nebular center toward the north. Weidentified for the first time two massive protostellar outflows of $\sim$10$^4$yr dynamical age along one of the most massive filaments. The observations alsorevealed several pillar-like CO features around the Nebula. The H II region andthe pillars have a complementary spatial distribution and the column density ofthe pillars is an order of magnitude higher than that of the pillars in theEagle nebula (M16) in the Galaxy, suggesting an early stage of pillar formationwith an age younger than $\sim$10$^5$ yr. We suggest that a cloud-cloudcollision triggered the formation of the filaments and protostar within thelast $\sim$2 Myr. It is possible that the collision is more recent, as part ofthe kpc-scale H I flows come from the tidal interaction resulting from theclose encounter between the LMC and SMC $\sim$200 Myr ago as suggested for R136by Fukui et al.
