LED wall that fits

Under a 3.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 3 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 27.4 m wall a Absen PL2.5 Plus V2 wall runs 43 x 3 (8600 x 600 px, 1,006 kg, 20.6 kW).

Absen PL2.5 Plus V2	2.5 mm	43 x 3 = 129	21.5 x 1.5 m	8600 x 600	1,006 kg / 2,218 lb	20.6 kW, 99 A @ 208 V

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.

Seating estimate

After a 12 x 7 m stage, The Library holds about 367 theater seats, 150 banquet seats at rounds of 10, or 103 classroom seats. Back row in theater is roughly 20.4 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
