When loading such straight sided rounds such as the 45 ACP how important is a case trimmer?
Assuming the cases are the correct length at the first firing, how often do they require trimming?

I used to shoot IPSC at about 50,000 rounds of 45 ACP a year. I bought a .452 pilot for my RCBS case trimmer but I never used it.

I have a 1911 that came home with me when I returned from SE Asia. It was pretty well used when I got it and has been shot a lot since. I've been loading ammo for it for at least 20 yrs. I have yet to trim a case. I load 230 gr round nose "hardball" or lead, and taper crimp. I'd guess some of the more refined 1911's could be sensitive to case length.

I have yet to trim any of my straight wall cases. The only round I use my trimmer for is my 300 ultra mag. I put calipers on my other bottle necks but I feel they are all within specs.

officialy its very important since the case headspaces on the mouth. unofficialy since pistol pressures are so low and there is negligable brass flow - not at all
I've never trimmed a 45acp case, usually lose them before they crack or lengthen. I have & do trim .357mag, 41 & 44mag & 45colts when shooting the higher pressure loads.
