4 with复合结构可以用作表语吗

Years of experience in the industry—and failed attempts to use technology—have convinced him that the best way to check cattle is with a man on a horse.

这是2021年新高考全国卷2阅读理解D的一个句子。前面一个网友问了 failed 的用法。但我觉得这里还有一个用法比较奇怪，那就是 with a man on a horse，这是 with 复合结构吧，它可以用作表语吗？求专家分析指点，谢谢！

附全段材料作参考：

For Texas cattleman Pete Bonds, it’s increasingly difficult to find workers interested in watching cattle. But Bonds doesn’t believe a robot is right for the job. Years of experience in the industry—and failed attempts to use technology—have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.
